### Building
|
||||
|
||||
- Generating cbindgen output
|
||||
- Install dependencies with `brew install cbindgen` or `apt-get install cbindgen` or `cargo install cbindgen` or the equivalent: we used `cargo install --version 0.23.0 cbindgen`.
|
||||
- Go to the directory where this README.md file is located
|
||||
- Generate with `cbindgen --config cbindgen.toml --crate serde-benchmark --output serde_benchmark.h`
|
||||
- Building
|
||||
- Run with `cargo build --release`

- A recent compiler (LLVM clang 6 or better, GNU GCC 7.4 or better, Xcode 11 or better) on a 64-bit (PPC, ARM or x64 Intel/AMD) POSIX systems such as macOS, freeBSD or Linux. We require that the compiler supports the C++11 standard or better.
|
||||
- Visual Studio 2017 or better under 64-bit Windows. Users should target a 64-bit build (x64 or ARM64) instead of a 32-bit build (x86). We support the LLVM clang compiler under Visual Studio (clangcl) as well as as the regular Visual Studio compiler. We also support MinGW 64-bit under Windows.

|

- A recent compiler (LLVM clang 6 or better, GNU GCC 7.4 or better, Xcode 11 or better) on POSIX systems such as macOS, FreeBSD or Linux. We require that the compiler supports the C++11 standard or better. We test the library on a big-endian system (IBM s390x with Linux).
|
||||
- Visual Studio 2017 or better. We support the LLVM clang compiler under Visual Studio (clang-cl) as well as as the regular Visual Studio compiler. For better release performance (both compile time and execution time), we recommend Visual Studio users adopt LLVM (clang-cl). We also support MinGW 64-bit under Windows.
|
||||
|
||||
Support for AVX-512 require a processor with AVX512-VBMI2 support (Ice Lake or better, AMD Zen 4 or better) under a 64-bit system and a recent compiler (LLVM clang 6 or better, GCC 8 or better, Visual Studio 2019 or better). You need a correspondingly recent assembler such as gas (2.30+) or nasm (2.14+): recent compilers usually come with recent assemblers. If you mix a recent compiler with an incompatible/old assembler (e.g., when using a recent compiler with an old Linux distribution), you may get errors at build time because the compiler produces instructions that the assembler does not recognize: you should update your assembler to match your compiler (e.g., upgrade binutils to version 2.30 or better under Linux) or use an older compiler matching the capabilities of your assembler.

Whenever you pass an `std::string` reference to `parser::iterate`,

the parser will access the bytes beyond the end of

the string but before the end of the allocated memory (`std::string::capacity()`).
|
||||
If you are using a sanitizer that checks for reading uninitialized bytes or `std::string`'s
|
||||
container-overflow checks, you may encounter sanitizer warnings.
|
||||
You can safely ignore these warnings. Or you can call `simdjson::pad(std::string&)` to pad the
|
||||
string with `SIMDJSON_PADDING` spaces: this function returns a `simdjson::padding_string_view` which can be be passed to the parser's iterator function:

### 2. Use `tag_invoke` for custom types (C++20)
|
||||
|
||||
The simdjson library takes advantage of C++20. An immediate benefit
|
||||
is that you can deserialize JSON data directly in standard containers
|
||||
and other standard value types:
|
||||
|
||||
```C++
|
||||
simdjson::padded_string json = R"({"data" : [1,2,3,4]})"_padded;
|
||||
|
||||
simdjson::ondemand::parser parser;
|

simdjson::ondemand::document d = parser.iterate(json);
|
||||
std::vector<uint8_t> array = d["data"].get<std::vector<uint8_t>>();
|
||||
```
|
||||
|
||||
Appending to an existing container is just as easy:
|
||||
|
||||
```C++
|
||||
std::vector<uint32_t> array = {0, 0};
|
||||
|
||||
simdjson::padded_string json = R"({"data" : [1,2,3,4]})"_padded;

||||
// array is now {0,0,1,2,3,4}
|
||||
```
|
||||
|
||||
In C++20, the standard introduced the notion of *customization point*.
|
||||
A customization point is a function or function object that can be customized for different types. It allows library authors to provide default behavior while giving users the ability to override this behavior for specific types.

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.
|
||||
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.
|
||||
- `append(char c)`: Appends a single character to the JSON buffer.
|
||||
- `append_null()`: Appends the string "null" to the JSON buffer.
|
||||
- `clear()`: Clears the contents of the JSON buffer, resetting the position to 0 while retaining the allocated capacity.
|
||||
- `escape_and_append(std::string_view input)`: Appends a string view to the JSON buffer after escaping special characters (e.g., quotes, backslashes) as required by JSON.
|
||||
- `escape_and_append_with_quotes(std::string_view input)` Appends a string view surrounded by double quotes (e.g., "input") to the JSON buffer after escaping special characters.
|
||||
Parameters:
|
||||
- `escape_and_append_with_quotes(char input)`: Appends a single character surrounded by double quotes (e.g., "c") to the JSON buffer after escaping it if necessary.
|
||||
- `append_raw(const char *c)`: Appends a null-terminated C string directly to the JSON buffer without escaping.
|
||||
- `append_raw(std::string_view input)`: Appends a string view directly to the JSON buffer without escaping.
|
||||
- `append_raw(const char *str, size_t len)`: Appends a specified number of characters from a C string directly to the JSON
|
||||
|
||||
After writting the content, if you have reasons to believe that the content might violate UTF-8 conventions, you can check it as follows:
|
||||
|
||||
- `validate_unicode()`: Checks if the content in the JSON buffer is valid UTF-8. Returns: true if the content is valid UTF-8, false otherwise.
|
||||
|
||||
You might need to do unicode validation if you have strings in your data structures containing
|
||||
malformed UTF-8.
|
||||
|
||||
Once you are satisfied, you can recover the string as follows:
|
||||
|
||||
- `operator std::string()`: Converts the JSON buffer to an std::string. (Might throw if an error occurred.)
|
||||
- `operator std::string_view()`: Converts the JSON buffer to an std::string_view. (Might throw if an error occurred.)
|
||||
- `view()`: Returns a view of the written JSON buffer as a `simdjson_result<std::string_view>`.
|
||||
|
||||
The later method (`view()`) is recommended.

|
||||
|
||||
void serialize_car(const Car& car, simdjson::builder::string_builder& builder) {
|
||||

|
||||
builder.start_object();
|
||||
|
||||

|
||||
builder.append_key_value("make", car.make);
|
||||
builder.append_comma();
|
||||
|
||||
// "model"
|
||||
builder.append_key_value("model", car.model);
|
||||
builder.append_comma();
|
||||
|
||||
// "year"
|
||||
builder.append_key_value("year", car.year);
|
||||
builder.append_comma();
|
||||
|
||||
// "tire_pressure"
|
||||

|
||||
builder.append_colon();
|
||||
builder.start_array();
|
||||
// vector tire_pressure
|
||||
for (size_t i = 0; i < car.tire_pressure.size(); ++i) {
|
||||
builder.append(car.tire_pressure[i]);
|
||||
if (i < car.tire_pressure.size() - 1) {
|
||||
builder.append_comma();
|
||||
}
|
||||
}
|
||||
builder.end_array();
|
||||
builder.end_object();
|
||||
}
|
||||
|
||||
bool car_test() {
|
||||
simdjson::builder::string_builder sb;
|
||||
Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
|
||||
serialize_car(c, sb);
|
||||
std::string_view p{sb};
|
||||
// p holds the JSON:
|
||||
// "{\"make\":\"Toyota\",\"model\":\"Corolla\",\"year\":2017,\"tire_pressure\":[30.0,30.2,30.513,30.79]}"
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
The `string_builder` constructor takes an optional parameter which specifies the initial
|
||||
memory allocation in byte. If you know approximately the size of your JSON output, you can
|
||||
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
|
||||
std::string_view p;
|
||||
if(sb.view().get(p)) {
|
||||
return false; // there was an error
|
||||
}
|
||||
```
|
||||
|
||||
In all cases, the `std::string_view` instance depends the corresponding `string_builder` instance.
|
||||
|
||||
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:
|
||||
|
||||
```cpp
|
||||
#define SIMDJSON_STATIC_REFLECTION 1
|
||||
//...
|
||||
#include "simdjson.h"
|
||||
```
|
||||
|
||||
And then you can append your data structures to a `string_builder` instance
|
||||
automatically. In most cases, it should work automatically:
|
||||
|
||||
```cpp
|
||||
struct Car {
|
||||
std::string make;
|
||||
std::string model;
|
||||
int64_t year;
|
||||
std::vector<double> tire_pressure;
|
||||
};
|
||||
|
||||
bool car_test() {
|
||||
simdjson::builder::string_builder sb;
|
||||
Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
|
||||
sb << c;
|
||||
std::string_view p{sb};
|
||||
// p holds the JSON:
|
||||
// "{\"make\":\"Toyota\",\"model\":\"Corolla\",\"year\":2017,\"tire_pressure\":[30.0,30.2,30.513,30.79]}"
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### Without `string_buffer` instance
|
||||
|
||||
In some instances, you might want to create a string directly from your own data type.
|
||||
You can create a string directly, without an explicit `string_builder` instance
|
||||
with the `simdjson::builder::to_json_string` function.
|
||||
(Under the hood a `string_builder` instance may still be created.)
|
||||
|
||||
```cpp
|
||||
struct Car {
|
||||
std::string make;
|
||||
std::string model;
|
||||
int64_t year;
|
||||
std::vector<double> tire_pressure;
|
||||
};
|
||||
|
||||
void f() {
|
||||
Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
|
||||
std::string json = simdjson::builder::to_json_string(c);
|
||||
}
|
||||
```
|
||||
|
||||
If you know the output size, in bytes, of your JSON string, you may
|
||||
pass it as a second parameter (e.g., `simdjson::builder::to_json_string(c, 31123)`).
|
||||
|
||||
|
||||
|
||||
### Without `string_buffer` instance but with explicit error handling
|
||||
|
||||
If prefer a version without exceptions and explicit error handling, you can use the following
|
||||
pattern:
|
||||
|
||||
```cpp
|
||||
std::string json;
|
||||
if(simdjson::builder::to_json_string(c).get(json)) {
|
||||
// there was an error
|
||||
} else {
|
||||
// json contain the serialized JSON
|
||||
}

```cpp

simdjson::dom::parser parser;

simdjson::dom::element doc = parser.parse(my_padded_data);

```
|

Whenever you pass an `std::string` reference to `parser::parse`,
|
||||
the parser will access the bytes beyond the end of
|
||||
the string but before the end of the allocated memory (`std::string::capacity()`).
|
||||
If you are using a sanitizer that checks for reading uninitialized bytes or `std::string`'s
|
||||
container-overflow checks, you may encounter sanitizer warnings.
|
||||
You can safely ignore these warnings. Or you can call `simdjson::pad(std::string&)` to pad the
|
||||
string with `SIMDJSON_PADDING` spaces: this function returns a `simdjson::padding_string_view` which can be be passed to the parser's iterator function:

dom::element doc = parser.parse(simdjson::pad(json));

```

The parsed document resulting from the `parser.load` and `parser.parse` calls depends on the `parser` instance. Thus the `parser` instance must remain in scope. Furthermore, you must have at most one parsed document in play per `parser` instance.

In the simdjson library, we check the `NDEBUG` macro as well as other
