This is a port of FlatBuffers to Rust. It provides code generation and a
runtime library derived from the C++ implementation. It utilizes the
Rust type system to provide safe and fast traversal of FlatBuffers data.
There are 188 tests, including many fuzz tests of roundtrips for various
serialization scenarios. Initial benchmarks indicate that the canonical
example payload can be written in ~700ns, and traversed in ~100ns.
Rustaceans may be interested in the Follow, Push, and SafeSliceAccess
traits. These traits lift traversals, reads, writes, and slice accesses
into the type system, providing abstraction with no runtime penalty.
* starting Lua port of python implmention. Syncing commit
* Bulk of Lua module port from Python done. Not tested, only static analysis. Need to work on binary strings. Started work on flatc lua code generation
* Fixed all the basic errors to produced a binary output from the builder, don't know if it is generated correctly, but it contains data, so that must be good
* fixed binary set command that was extending the array improperly
* continued improvement
* Moved lua submodules down a directory so their names don't clash with potential other modules. Added compat module to provide Lua versioning logic
* Successful sample port from Python
* working on testing Lua code with formal tests
* continued to work on tests and fixes to code to make tests pass
* Added reading buffer test
* Changed binaryarray implmentation to use a temporary table for storing data, and then serialize it to a string when requested. This double the rate of building flatbuffers compared to the string approach.
* Didn't need encode module as it just added another layer of indirection that isn't need
* profiled reading buffers, optimizations to increase read performance of monster data to ~7 monster / millisecond
* Writing profiler improvments. Get about
~2 monsters/millisecond building rate
* removed Numpy generation from Lua (came from the Python port)
* math.pow is deprecated in Lua 5.3, so changed to ^ notation. Also added .bat script for starting Lua tests
* adding results of generate_code.bat
* simple edits for code review in PR.
* There was a buffer overflow in inserting the keywords into the unorder set for both the Lua and Python code gens. Changed insertion to use iterators.
* fixed spacing issue
* basic documenation/tutorial updates. Updated sample_binary.lua to reflect the tutorial better
* removed windows-specific build step in Lua tests
* Python: Generated enum member names are now escaped if they correspond to a Python keyword.
* Keyword list in Python generator is now a const char* instead of an std::string array.
* Moved static functions and keyword list of Python generator into the PythonGenerator class.
* Python generator escapes keyword identifiers in all definitions.
* Fix issue #4389, if field is ommitted the return type is the same for python generator
* Fix issue #4389, bytes is returned when field is omitted
* Fix issue #4389, added generated python code after generator modification
A Namespace object is now guaranteed unique.
This cleaned up some old workarounds and latent bugs.

* Add numpy accessor to python flatbuffers scalar vectors
* Update python tests to test numpy vector accessor
* Update appveyor CI to run Python tests, save generated code as artifact
* Update example generated python code
* Add numpy info to python usage docs
* Update test schema and python tests w/ multi-byte vector
* did not mean to push profiling code
* adding float64 numpy tests
* Added <autogenerated> in cs generator file header comment
#4287
* CS: Added xml-correct file header comment including "<auto-generated>...</auto-generated>"
code_generators.cpp: FlatBuffersGeneratedWarning() function replaced by compile time constant "GeneratedWarning"
also removed extra newlines at end of GeneratedWarning to be able to generate a xml well formed file comment for cs files
#4291
* code_generators: Changed static string GeneratedWarning back to function FlatBuffersGeneratedWarning()
#4291
* Added modified Unit-Test files
#4291
* idl_gen_general: Add autogenerated only in C# code
#4291
Also fixed most codegenerators using the wrong namespace when multiple
namespace were used in a file, with some files not being generated.

Bug: 29338474
Implement code generation and self-contained runtime library for Python.
The test suite verifies:
- Correctness of generated Python code by comparing output to that of
the other language ports.
- The exact bytes in the Builder buffer during many scenarios.
- Vtable deduplication correctness.
- Edge cases for table construction, via a fuzzer derived from the Go
implementation.
- All code is simultaneously valid in Python 2.6, 2.7, and 3.4.
The test suite includes benchmarks for:
- Building 'gold' data.
- Parsing 'gold' data.
- Deduplicating vtables.
All tests pass on this author's system for the following Python
implementations:
- CPython 2.6.7
- CPython 2.7.8
- CPython 3.4.2
- PyPy 2.5.0 (CPython 2.7.8 compatible)
