* Documenting our support of JSON Path and JSON Pointer vs. Unicode characters
* using more standard terminology (nitpicking)
* specifying UTF-8 encoding
* allow char8_t when compiling as C++20
* casting
* minor doc corrections
* First implementation of the conversion logic.
- Not yet tested
- Not yet compiled
- Not yet used in ondemand array/object/etc...
* Adding at_path to ondemand arrays
* Adding at_path to array, document and value.
* Adding at_path to ondemand object as well.
Pending:
- Building
- Adding tests for each of the on-demand classes usage of at_path
- Properly documenting the subset of json path that is currently supported.
* Adding a simple json_path test to on_demand
* Still trying to compile the ondemand_readme_examples test with the at_path() call
* Fixing linking issues with array::at_path
* Fixing issues with the path -> pointer conversion and removing comments
* Adding a clone of json_pointer to test json_path extensively
* Adding ondemand_json_path_tests (all tests passing)
* Adding documentation for at_path()
* Removing some newlines
* Removing simdjson_result from the return type of the string conversion function. Now json_path_to_pointer_conversion returns a std::string.
* Fixing typo
* Making string concatenation explicit to avoid ubuntu gcc12 issue with -O3 flag.
* Addressing latest reviews

* Rename simdjson_really_inline -> simdjson_inline
I want to change the simdjson_really_inline macro to sometimes not force
inlining. After that upcoming change, the name simdjson_really_inline
will no longer makes sense.
Rename simdjson_really_inline to simdjson_inline. This patch should not
change semantics; simdjson_inline still forces inlining as before.
Some functions still need to be really inlined for ABI reasons.
(GCC's -Wpsabi complains otherwise.) Leave those functions marked as
simdjson_really_inline.
* Improve build times for debug builds
simdjson_inline is used for most simdjson functions. It forces inlining.
In unoptimized/debug builds, this can lead to a lot of machine code
being generated (especially with Address Sanitizer), causing slow
compilation.
Change simdjson_inline to force inlining only for optimized builds.
Sometimes, the programmer might want a slightly-optimized build and want
fast compilation (e.g. GCC's -Og mode). Allow simdjson users to define
the simdjson_inline macro themselves (e.g. on the command line:
-Dsimdjson_inline=inline) in cases where the default behavior is
undesired.
This patch reduced build times by over 75% for ondemand_object_tests.cpp
with GCC 9.4.0 and CMAKE_BUILD_TYPE=Debug on my AMD 5950X:
Before: 6.885 6.683 6.971 6.957 6.949 seconds (5 samples)
After: 1.492 1.551 1.494 1.490 1.531 seconds (5 samples)
* This exposes 'rewind' for object and array instances.
* Putting really_inline back to count_elements()
* Update array.h
* Adding empty array rewind.
* Adds "is_empty" method to arrays.
* More fragmentation.
* Tweaking implementation.
* Fixing issue with get_value() on document instances.
* Changing the name of the new rewind functions to reset.
* Changing the name of the function to 'to_json_string' from 'to_string' to avoid confusion.
* Moving to a fast string_view model
* Making it exception-safe.
* Tweaking.
* Workaround for exceptions.
* more robust to_json_string (#1651)
* WIP.
* Fuzzing timeout (bug fix) (#1650)
* prove pull request #1648 introduces an infinite loop
* Interesting bug!
* Tweak.

This avoids a very unlikely buffer overrun that can occur in a particular kind of invalid JSON:
- the document is invalid with an unclosed top level array or object
- the last thing in the document is a number that ends at EOF
- the padding is filled entirely with numeric digits
