-Assertions and development checks

-
-We do not use conventional `assert` in simdjson. Instead we use the macro
-`SIMDJSON_ASSUME`:
-
-```cpp
-SIMDJSON_ASSUME(something_that_is_true());
-```
-
-Sometimes, you need to do a bit more work that a simple check.
-The `SIMDJSON_DEVELOPMENT_CHECKS` macro is true only in Debug mode unless manually set.
-It is acceptable to add checks that you would not do in Release mode as long as

-
-```cpp
-#if SIMDJSON_DEVELOPMENT_CHECKS
-// do sanity checks here

-Working with sanitizers

-The simdjson library must be memory-safe. We cannot allow buffer overruns.
-During development, if you system supports it, we recommend configuring

-# Accessor Performance Benchmarks (C++26)
-
-These benchmarks compare the performance of runtime vs compile-time JSON accessors.
-For the comparison to be meaningful, you must build simdjson with support for
-C++26 reflexion. See the `p2996` repository in the main project directory.
-
-## Files
-
-- `accessor_benchmark.h` - Common benchmark framework and test data
-- `runtime_accessors.h` - Runtime `at_path()` benchmarks
-- `compile_time_accessors.h` - Compile-time `at_path_compiled()` benchmarks (requires C++26 reflection)
-
-## Benchmarks
-
-Each benchmark measures parsing + single field access:
-
-1. **accessor_simple** - Simple field: `.name`
-2. **accessor_nested** - Nested field: `.address.city`
-3. **accessor_deep** - Deep nested field: `.address.coordinates.lat`
-
-## Building (Linux/macOS)
-
-```bash
-cmake -B build -D SIMDJSON_STATIC_REFLECTION=ON -DSIMDJSON_DEVELOPER_MODE=ON
-cmake --build build --target=bench_ondemand
-```
-
-The `SIMDJSON_STATIC_REFLECTION` will be made unnecessary once mainstream compilers
-begin supporting C++26 sufficiently well.
-
-## Running (Linux/macOS)
-
-
-```bash
-# Run all accessor benchmarks
-./build/bench_ondemand --benchmark_filter="accessor"
-```
-
-## Results
-
-We find that compile-time accessors show performance improvements that scale with path depth:
-- Simple fields: ~1.2x faster
-- Nested fields: ~1.5x faster
-- Deep nested fields: ~1.8x faster
-
-The speedup comes from eliminating runtime path parsing and conversion overhead.

 Overview: string_builder
 ---------------------------
 
 The string_builder class is a low-level utility for constructing JSON strings representing documents. It is optimized for performance, potentially leveraging kernel-specific features like SIMD instructions for tasks such as string escaping. This class supports atomic types (e.g., booleans, numbers, strings) but does not handle composed types directly (like arrays or objects).
-Note that JSON strings are always encoded as UTF-8.
 
 An `string_builder` is created with an initial buffer capacity (e.g., 1kB). The memory
-is reallocated when needed.
+is reallocated when needed. It has the following methods to add content to the string:
-The efficiency of `string_builder` stems from its internal use of a resizable array or buffer. When you append data, it adds the characters to this buffer, resizing it only when necessary, typically in a way that minimizes reallocations. This approach contrasts with regular string concatenation, where each operation creates a new string, copying all previous content, leading to quadratic time complexity for repeated concatenations.

-It has the following methods to add content to the string:
 
 
 - `append(number_type v)`: Appends a number (including booleans) to the JSON buffer. Booleans are converted to the strings "false" or "true". Numbers are formatted according to the JSON standard, with floating-point numbers using the shortest representation that accurately reflects the value.

-pass this value as a parameter (e.g., `simdjson::builder::string_builder sb{1233213}`).
-
-The `string_builder` might throw an exception in case of error when you cast it result to `std::string_view`. If you wish to avoid exceptions, you can use the following programming pattern:
-
-```cpp

+        return true;

+    }

-
-
-
-If you have C++20, you can simplify the code, as the `std::vector<double>` is automatically supported. Further, we can pass the keys (which are compile-time
-constant) as template parameter (for improved performance).
-
-```cpp

-    sb.append_key_value<"tire_pressure">(c.tire_pressure);
-    sb.end_object();
-    std::string_view p = sb.view();
-```
-
-With C++20, you can similarly handle standard containers transparently.
-For example, you can serialize `std::map<std::string,T>` types.
-
-```cpp
-    std::map<std::string,double> c = {{"key1", 1}, {"key2", 1}};
-    simdjson::builder::string_builder sb;
-    sb.append(c);
-    std::string_view p = sb.view();
-```
-
-You can also serialize `std::vector<T>` types.
-
-```cpp
-    std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-    simdjson::builder::string_builder sb;
-    sb.append(c);
-    std::string_view p = sb.view();
-```
-
-You can also skip the creation for the `string_builder` instance in such simple cases.
-
-```cpp
-std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-std::string json = simdjson::to_json(c);
-```
-
-We also have an overload for when you want to reuse the same `std::string` instance:
-
-
-```cpp
-std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-std::string json;
-auto error = simdjson::to_json(c, json);
-if(error) { /* there was an error */ }
-```
-
-
-We do recommend that you create and reuse the `string_builder` instance for performance
-reasons.
-
-You can also add custom serialization functions using a `tag_invoke` function.
-For example, the following
-function will allow you to serialize instances of the type `Car`.
-
-```cpp
-#include <simdjson>
-
-struct Car {
-  std::string make;

 C++26 static reflection
 ------------------------
 
-Static reflection (or compile-time reflection) in C++26 introduces a powerful compile-time mechanism that allows a program to inspect and manipulate its own structure, such as types, variables, functions, and other program elements, during compilation. Unlike runtime reflection in languages like Java or Python, C++26’s static reflection operates entirely at compile time, aligning with C++’s emphasis on zero-overhead abstractions and high performance. It means
-that you can delegate much of the work to the library.
 If you have a compiler with support C++26 static reflection, you can compile
 your code with the `SIMDJSON_STATIC_REFLECTION` macro set:

-## Introduction
-In some instances, you may want to configure your software at compile-time with a JSON document.
-Maybe you have a single code base but many different possible configurations, all resulting in
-different software. For example, you might be programming robots, using the same software, but
-different robot configurations.
-
-To achieve the desired result, you have a few options. You may start the software and parser a
-JSON file at runtime. Or you might convert your JSON data into C++ code that you can compile with
-your software.
-
-With C++26, there is another way: parse the JSON file along with your C++ code. In this manner,
-the JSON data becomes native C++ data.
-
-The simdjson library supports parsing JSON documents at compile time if you have C++26 support. To
-activate C++26 reflection support, you can compile
-your code with the `SIMDJSON_STATIC_REFLECTION` macro set:
-
-```cpp
-#define SIMDJSON_STATIC_REFLECTION 1
-//...
-#include "simdjson.h"
-```
-
-The `simdjson::compile_time::parse_json` function parses a JSON document at **compile time** and returns a `constexpr` structure reflecting its content. We support the full range of JSON values, which are mapped to C++ types as in
-the following table.
-
-
-| JSON type      | C++ type                         |
-|----------------|----------------------------------|
-| object         | anonymous struct                 |
-| array          | `std::array<T, N>` (homogeneous) |
-| string         | `const char*` (UTF-8)            |
-| number         | `int64_t`, `uint64_t`, `double`  |
-| `true`/`false` | `bool`                           |
-| `null`         | `std::nullptr_t`                 |
-
-## Example
-
-Suppose you want to parse the following JSON document:
-
-```cpp
-{
-    "port": 8080,
-    "host": "localhost",
-    "debug": true
-}
-```
-
-**Reminder**: In C++, `R"( )"` allows us to write multi-line strings with unescaped quotes.
-
-
-You can do so, at compile-time, as follows:
-
-
-```cpp
-constexpr auto cfg = R"(
-
-{
-    "port": 8080,
-    "host": "localhost",
-    "debug": true
-}
-
-)"_json;
-
-// cfg.port == 8080
-// std::string_view(cfg.host) == "localhost"
-// cfg.debug == true
-```
-
-You can nest objects and arrays:
-
-```cpp
-constexpr auto data = R"(
-
-{
-    "servers": [
-        {"host": "s1", "port": 3000},
-        {"host": "s2", "port": 3001}
-    ]
-}
-
-)"_json;
-
-
-// data.servers.size() == 2
-// std::string_view(data.servers[0].host) == "s1"
-```
-
-Top-level arrays are allowed:
-
-```cpp
-constexpr auto arr = R"(
-
-[1, 2, 3]
-
-)"_json;
-static_assert(arr.size() == 3);
-static_assert(arr[1] == 2);
-```
-
-
-## Concepts
-
-Given that the parsed data is made of structures that depend on the JSON input, you might
-want to check that it conforms to your expectation. You can do so with concepts.
-
-Let us consider this example:
-
-```cpp
-    constexpr auto config = R"(
-
-    [
-      { "name": "Alice", "age": 30 },
-      { "name": "Bob", "age": 25 },
-      { "name": "Charlie", "age": 35 }
-    ]
-
-    )"_json;
-```
-
-You might want to ensure that the result is an array of persons. You can define your
-expection with concepts like so:
-
-```cpp
-template <typename T>
-concept person = requires(T p) {
-    std::string_view(p.name);  // has name field convertible to string_view
-    p.age;                     // has age field
-    requires std::is_integral_v<decltype(p.age)>;  // age is integral
-};
-
-/**
- * Concept to validate that a type is an array of person objects
- */
-template <typename T>
-concept array_of_person = requires(T arr) {
-    arr.size();                    // has size method
-    arr[0];                        // can access elements with []
-    requires person<decltype(arr[0])>;  // elements satisfy person concept
-};
-```
-
-And then a simple static assert with `decltype` is sufficient to check that the expectation is met:
-
-```cpp
-  constexpr auto config = R"(
-
-  [
-    { "name": "Alice", "age": 30 },
-    { "name": "Bob", "age": 25 },
-    { "name": "Charlie", "age": 35 }
-  ]
-
-  )"_json;
-
-
-  // Validate that the array satisfies the array_of_person concept
-  static_assert(array_of_person<decltype(config)>);
-```
-
-
-
-## Loading from disk
-
-In practice, you may have a JSON file, say `json_data` that you want to parse
-at compile time. You may do so as follows.
-
-```c++
-constexpr const char json_data[] = {
-    #embed "test.json"
-    , 0
-};
-
-constexpr auto json = simdjson::compile_time::parse_json<json_data>();
-```
-
-
-## Limitations (compile-time errors)
-
-We have a few limitations which trigger compile-time errors if violated.
-
-
-- Only JSON objects and arrays are supported at the top level (no primitives).
-  We will lift this limitation in the future.
-- Strings are represented using the `const char*` in UTF-8, but they must not
-  contain embedded nulls. We would prefer to represent them as std::string or
-  std::string_view, and hope to do so in the future.
-- Heterogeneous arrays are not supported yet. E.g., you need to have arrays of
-  all integers, or all strings, all floats, all compatible objects, etc.
-  For example, the following is accepted:
-  ```json
-   [
-    { "name": "Alice", "age": 30 },
-    { "name": "Bob", "age": 25 },
-    { "name": "Charlie", "age": 35 }
-  ]
-  ```
-  but the following is not:
-  ```json
-  [
-    { "name": "Alice", "age": 30 },
-    "Just a string",
-    42,
-    { "name": "Charlie", "age": 35 }
-  ]
-  ```
-  We may support heterogeneous arrays in the future with std::variant types.
-- We parse the first JSON document encountered in the string. Trailing
-  characters are ignored. Thus if your JSON begins with {"a":1}, everything
-  after the closing brace is ignored. This limitation will be lifted in the future,
-  reporting an error.
-
-These limitations are safe in the sense that they result in compile-time errors.
-Thus you will not get truncated strings or imprecise floats silently.
-
-
-Although we are committed to maintaining the functionality in the long run, the
-`compile_time::parse_json` function is subject to change.

-# Compile-Time JSONPath and JSON Pointer Accessors
-
-**Note:** This feature requires C++26 Static Reflection support (P2996) and is currently only available with experimental compilers. You must enable it with `-DSIMDJSON_STATIC_REFLECTION=ON` when building.
-
-## Overview
-
-simdjson provides compile-time JSONPath and JSON Pointer accessors that validate paths against struct definitions at compile time and generate optimized accessor code with zero runtime overhead. This combines the safety of compile-time type checking with the performance of pre-parsed, pre-validated access paths.
-
-## Requirements
-
-- C++26 compiler with Static Reflection support (P2996)
-- Experimental compiler flags:
-  - Clang with P2996 support: `-std=c++26 -freflection -fexpansion-statements`
-- Build configuration: `-DSIMDJSON_STATIC_REFLECTION=ON`
-
-## How It Works
-
-**Compile Time:**
-1. Path string is parsed and converted to access steps
-2. Path is validated against struct definition using reflection
-3. Field types are checked and verified
-4. Optimized accessor code is generated
-
-**Runtime:**
-- Direct navigation with no parsing
-- No validation overhead
-- No string comparisons for path components
-- Type-safe extraction
-
-## Two Usage Modes
-
-### Mode 1: With Type Validation (Recommended)
-
-When you provide a struct type, the compiler validates the entire path at compile time:
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-  std::vector<std::string> emails;
-};
-
-//  R"( ... )" is a C++ raw string literal.
-const padded_string json = R"({
-  "name": "Alice",
-  "age": 30,
-  "emails": ["alice@example.com", "alice@work.com"]
-})"_padded;
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// Compile-time validation: checks that User has "name" field of type std::string
-std::string name;
-auto result = ondemand::json_path::at_path_compiled<User, ".name">(doc);
-result.get(name); // name = "Alice"
-
-// Compile-time validation: checks that "emails" is array-like with string elements
-std::string email;
-result = ondemand::json_path::at_path_compiled<User, ".emails[0]">(doc);
-result.get(email); // email = "alice@example.com"
-```
-
-**Benefits:**
-- **Compile-time errors** if path doesn't exist in struct
-- **Type safety** - verifies field types match expected types
-- **Refactoring protection** - renaming struct fields causes compile errors
-
-**What gets validated:**
-- Field existence
-- Field types
-- Array/container access validity
-- Nested struct navigation
-
-### Mode 2: Without Validation
-
-When you omit the struct type, the path is parsed at compile time but not validated:
-
-```cpp
-const padded_string json = R"({
-  "name": "Alice",
-  "age": 30,
-  "address": {"city": "Boston"}
-})"_padded;
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// No compile-time validation - path is only parsed
-std::string name;
-auto result = ondemand::json_path::at_path_compiled<".name">(doc);
-result.get(name); // name = "Alice"
-
-std::string_view city;
-result = ondemand::json_path::at_path_compiled<".address.city">(doc);
-result.get(city); // city = "Boston"
-```
-
-**Benefits:**
-- Works with dynamic/unknown JSON structures
-- Still benefits from compile-time path parsing
-- No runtime string parsing overhead
-
-**Use when:**
-- JSON structure is not known at compile time
-- Working with varied JSON schemas
-- Prototyping or exploratory parsing
-
-## JSONPath Syntax
-
-JSONPath uses dot notation and bracket notation for field access:
-
-### Supported Syntax
-
-| Syntax | Description | Example |
-|--------|-------------|---------|
-| `.field` | Dot notation for field access | `.name`, `.address.city` |
-| `["field"]` | Bracket notation with quotes | `["name"]`, `["address"]["city"]` |
-| `[index]` | Array index access | `[0]`, `[1]` |
-| Mixed | Combination of notations | `.emails[0]`, `["users"][0].name` |
-| `$` prefix | Optional root indicator | `$.name`, `$["name"]` |
-
-### Examples
-
-```cpp
-struct Address {
-  std::string city;
-  int zip;
-};
-
-struct Person {
-  std::string name;
-  int age;
-  Address address;
-  std::vector<std::string> emails;
-};
-
-// Dot notation
-at_path_compiled<Person, ".name">(doc)
-at_path_compiled<Person, ".address.city">(doc)
-
-// Bracket notation
-at_path_compiled<Person, "[\"name\"]">(doc)
-at_path_compiled<Person, "[\"address\"][\"city\"]">(doc)
-
-// Array access
-at_path_compiled<Person, ".emails[0]">(doc)
-at_path_compiled<Person, ".emails[1]">(doc)
-
-// Mixed notation
-at_path_compiled<Person, ".address[\"zip\"]">(doc)
-at_path_compiled<Person, "[\"emails\"][0]">(doc)
-
-// With root indicator
-at_path_compiled<Person, "$.name">(doc)
-at_path_compiled<Person, "$.address.city">(doc)
-```
-
-## JSON Pointer Syntax
-
-JSON Pointer (RFC 6901) uses slash-separated paths:
-
-### Supported Syntax
-
-| Syntax | Description | Example |
-|--------|-------------|---------|
-| `/field` | Field access | `/name`, `/address/city` |
-| `/index` | Array index | `/0`, `/1` |
-| `~0` | Escaped `~` | `/field~0name` → field~name |
-| `~1` | Escaped `/` | `/field~1name` → field/name |
-
-### Examples
-
-```cpp
-struct Car {
-  std::string make;
-  std::string model;
-  int64_t year;
-  std::vector<double> tire_pressure;
-};
-
-// Field access
-at_pointer_compiled<Car, "/make">(doc)
-at_pointer_compiled<Car, "/model">(doc)
-
-// Array access
-at_pointer_compiled<Car, "/tire_pressure/0">(doc)
-at_pointer_compiled<Car, "/tire_pressure/1">(doc)
-
-// Root pointer (returns whole document)
-at_pointer_compiled<Car, "">(doc)
-at_pointer_compiled<Car, "/">(doc)
-```

-
-```cpp
-// With type validation
-template<typename T, constevalutil::fixed_string Path, typename DocOrValue>
-simdjson_result<value> at_path_compiled(DocOrValue& doc_or_val);
-
-// Without validation
-template<constevalutil::fixed_string Path, typename DocOrValue>
-simdjson_result<value> at_path_compiled(DocOrValue& doc_or_val);
-```
-
-### JSON Pointer Functions
-
-```cpp
-// With type validation
-template<typename T, constevalutil::fixed_string Pointer, typename DocOrValue>
-simdjson_result<value> at_pointer_compiled(DocOrValue& doc_or_val);
-
-// Without validation
-template<constevalutil::fixed_string Pointer, typename DocOrValue>
-simdjson_result<value> at_pointer_compiled(DocOrValue& doc_or_val);
-```
-
-### Direct Field Extraction
-
-Extract values directly into variables with compile-time type checking:
-
-```cpp
-// JSONPath
-template<typename T, constevalutil::fixed_string Path>
-struct path_accessor {
-  template<typename DocOrValue, typename FieldType>
-  static error_code extract_field(DocOrValue& doc_or_val, FieldType& target);
-};
-
-// JSON Pointer
-template<typename T, constevalutil::fixed_string Pointer>
-struct pointer_accessor {
-  template<typename DocOrValue, typename FieldType>
-  static error_code extract_field(DocOrValue& doc_or_val, FieldType& target);
-};
-```
-
-**Example:**
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-};
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// Extract directly into variable
-std::string name;
-ondemand::json_path::path_accessor<User, ".name">::extract_field(doc, name);
-
-int age;
-ondemand::json_path::pointer_accessor<User, "/age">::extract_field(doc, age);
-```
-
-The compiler verifies that the target variable type matches the field type at the path.
-
-## Complete Examples
-
-### Example 1: Validated Access

-  result.get(pressure); // pressure = 39.9
-
-  return 0;

-```
-
-### Example 2: Non-Validated Access
-

-using namespace simdjson;
-
-int main() {
-  const padded_string json = R"({
-    "user": {
-      "name": "Alice",

-  // email = "bob@example.com"
-
-  return 0;

-## Error Handling
-
-Compile-time errors occur when:
-- Path doesn't exist in struct: `static_assert` failure
-- Field type mismatch: `static_assert` failure
-- Invalid array access on non-array field: `static_assert` failure
-
-Runtime errors occur when:
-- JSON structure doesn't match expected structure
-- Array index out of bounds
-- Type conversion failures
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-};
-
-// Compile-time error: no "email" field in User
-// auto result = ondemand::json_path::at_path_compiled<User, ".email">(doc);
-
-// Compile-time error: age is not an array
-// auto result = ondemand::json_path::at_path_compiled<User, ".age[0]">(doc);
-
-// Runtime error if JSON doesn't have "name" field
-auto result = ondemand::json_path::at_path_compiled<User, ".name">(doc);
-std::string name;
-if (result.get(name) != SUCCESS) {
-  // Handle error
-}
-```
-
-## Performance
-
-Compile-time accessors provide:
-- **Zero path parsing overhead** - paths parsed at compile time
-- **Zero validation overhead** - validation done at compile time
-- **Direct field access** - no runtime path traversal
-- **Type-safe extraction** - no dynamic type checking
-
-Compared to runtime `at_path()` and `at_pointer()`:
-- Eliminates runtime path string parsing
-- Eliminates runtime path validation
-- Generates optimal code path directly
-
-## Limitations
-
-- Requires C++26 compiler with P2996 support (experimental)
-- Paths must be compile-time constants (string literals)
-- Cannot use runtime-computed paths
-- Limited to struct types that support reflection
-- Array indices must be compile-time constants in the path
-
-## When to Use
-
-**Use compile-time accessors when:**
-- You have well-defined struct types
-- JSON structure is known at compile time
-- You want maximum type safety
-- Performance is critical
-
-**Use runtime `at_path()`/`at_pointer()` when:**
-- JSON structure varies or is unknown
-- Paths are computed at runtime
-- Working with C++20 or earlier
-- Flexibility is more important than compile-time checks

-## Using `at_path_with_wildcard` for JSONPath Queries
-
-The `at_path_with_wildcard` function in simdjson extends the JSONPath querying capabilities by supporting wildcard expressions (`*`) in JSON paths. This allows users to retrieve multiple elements from a JSON document in a single query. For example, you can use `$.address.*` to fetch all fields within the `address` object or `$.phoneNumbers[*].numbers[*]` to retrieve all phone numbers across multiple objects in an array.
-
-The `*` wildcard matches all elements at a specific level. For instance, `$.address.*` retrieves all key-value pairs in the `address` object, while `$.*.streetAddress` fetches all `streetAddress` fields across objects at the root level.  You can combine wildcards with array indexing. For example, `$.phoneNumbers[*].numbers[1]` retrieves the second number from each `numbers` array in the `phoneNumbers` array. If no elements match the wildcard query, the function returns an empty result. For instance, querying `$.empty_object.*` or `$.empty_array.*` will yield an empty set.
-
-### Example Usage
-
-Here is an example demonstrating the use of `at_path_with_wildcard`:
-
-```cpp

-{
-  "firstName": "John",
-  "lastName": "doe",

-      "numbers": ["0123-4567-8910"]
-    }
-  ]
-})"_padded;
-
-dom::parser parser;
-dom::element parsed_json = parser.parse(json_string);
-std::vector<dom::element> values;
-
-// Fetch all fields in the address object
-auto error = parsed_json.at_path_with_wildcard("$.address.*").get(values);
-if(error) {
-  // do something
-}
-for (auto &value : values) {
-  std::string_view field;
-  error = value.get(field);
-  if(error) {
-    // do something
-  }
-  std::cout << field << std::endl;
-}
-
-// Fetch all phone numbers
-error = parsed_json.at_path_with_wildcard("$.phoneNumbers[*].numbers[*]").get(values);
-if(error) {
-  // do something
-}
-for (auto &value : values) {
-  std::string_view number;
-  error = value.get(number);
-  if(error) {
-    // do something
-  }
-  std::cout << number << std::endl;
-}
-```
-
-This function is particularly useful for extracting data from complex JSON structures with nested arrays and objects. By leveraging wildcards, you can simplify your queries and reduce the need for multiple iterations.

Under x64 processors, many programmers will want to target `haswell` whereas under ARM, most programmers will want to target `arm64` (and it should do so automatically).

- * @brief Compile-time JSON parser. This function parses the provided JSON
- * string at compile time and returns a custom struct type representing the JSON
- * object.
- *
- * We have a few limitations which trigger compile-time errors if violated:
- * - Only JSON objects and arrays are supported at the top level (no primitives).
- *   We will lift this limitation in the future.
- * - Strings are represented using the const char * in UTF-8, but they must not
- *   contain embedded nulls. We would prefer to represent them as std::string or
- *   std::string_view, and hope to do so in the future.
- * - Heterogeneous arrays are not supported yet. E.g., you need to have arrays of
- *   all integers, or all strings, all floats, all compatible objects, etc.
- *   For example, the following is accepted:
- *    [
- *     { "name": "Alice", "age": 30 },
- *     { "name": "Bob", "age": 25 },
- *     { "name": "Charlie", "age": 35 }
- *   ]
- *   but the following is not:
- *   [
- *     { "name": "Alice", "age": 30 },
- *     "Just a string",
- *     42,
- *     { "name": "Charlie", "age": 35 }
- *   ]
- *
- *    We may support heterogeneous arrays in the future with std::variant types.
- * - We parse the first JSON document encountered in the string. Trailing
- *   characters are ignored. Thus if your JSON begins with {"a":1}, everything
- *   after the closing } is ignored. This limitation will be lifted in the future,
- *   reporting an error.
- *
- * These limitations are safe in the sense that they result in compile-time errors.
- * Thus you will not get truncated strings or imprecise floats silently.
- *
- * This function is subject to change in the future.

- * The simdjson::from instance is EXPERIMENTAL AND SUBJECT TO CHANGES.
- *
- * The `from` instance is a utility adaptor for parsing JSON strings into objects.
- * It provides a convenient way to convert JSON data into C++ objects using the `auto_parser`.
- *
- * Example usage:
- *
- * ```cpp
- * std::map<std::string, std::string> obj =
- *   simdjson::from(R"({"key": "value"})"_padded);
- * ```
- *
- * This will parse the JSON string and return an object representation. By default, we
- * use the simdjson::ondemand::parser::get_parser() instance. A parser instance should
- * be used for just one document at a time.
- *
- * You can also pass you own parser instance:
- * ```cpp
- * simdjson::ondemand::parser parser;
- * std::map<std::string, std::string> obj =
- *   simdjson::from(parser, R"({"key": "value"})"_padded);
- * ```
- * The parser instance can be reused.
- *
- * This functionality requires C++20 or better.

-/**
- * Compile-time JSON Path and JSON Pointer accessors using C++26 reflection (P2996)
- *
- * This file validates JSON paths/pointers against struct definitions at compile time
- * and generates optimized accessor code with zero runtime overhead.
- *
- * ## How It Works
- *
- * **Compile Time**: Path is parsed, validated against struct, types are checked
- * **Runtime**: Direct navigation with no parsing or validation overhead
- *
- * Example:
- * ```cpp
- * struct User { std::string name; std::vector<std::string> emails; };
- *
- * std::string email;
- * path_accessor<User, ".emails[0]">::extract_field(doc, email);
- *
- * // Compile time validates:
- * // 1. User has "emails" field
- * // 2. "emails" is array-like
- * // 3. Element type is std::string
- * // 4. static_assert(^^std::string == ^^std::string)
- *
- * // Runtime just navigates:
- * // doc.get_object().find_field("emails").get_array().at(0).get(email)
- * ```
- *
- * ## Key Reflection APIs
- *
- * - `^^Type`: Reflect operator, converts type to std::meta::info
- * - `std::meta::nonstatic_data_members_of(type)`: Get all fields of a struct
- * - `std::meta::identifier_of(member)`: Get field name as string_view
- * - `std::meta::type_of(member)`: Get reflected type of a field
- * - `std::meta::is_array_type(type)`: Check if C-style array
- * - `std::meta::remove_extent(array)`: Extract element type from array
- * - `std::meta::members_of(type)`: Get all members including typedefs
- * - `std::meta::is_type(member)`: Check if member is a type (vs field)
- *
- * All operations execute at compile time in consteval contexts.
