* [C#] Add GetBytes methods for fixed arrays
I wanted to direct access to fixed array bytes. I made some changes to the idl generator to create GetBytes functions following the same naming conventions used for vectors of scalar types. There was not a 'Length' field present to bound the existing index accessor so I added that too.
+ Add generic GetBytes for fixed length arrays of scalar types
+ Implement conditional compilation for ENABLE_SPAN_T:
- ENABLE_SPAN_T: Returns `Span<T>` using `MemoryMarshal.Cast<byte, T>()` as needed.
- Else: Returns `ArraySegment<byte>?` for raw byte access
+ Added tests reusing arrays_test.fbs definitions
+ Added const int Length field to support existing index based accessors
* [C#] Sync generated code for after adding GetBytes methods for fixed arrays

* Adds tests for Rust single file mode
All existing tests only compile Rust code using --rust-module-root-file.
* Adds standalone include tests for Rust
The imports for these tests have been moved to their own file, as the existing intergration_test.rs file hides compilation issues from code generation due to symbols brought into scope outside of the generated code (e.g. `extern crate alloc`).
* Declare alloc crate in every Rust namespace
When performing code generation within a single file, extern crate alloc needs to be delcared to bring alloc into scope within every inner namespace.
* Regenerates generated schemas
The write_vtable() function's comment claimed to "fill the WIP vtable
with zeros" but make_space() only reserves memory without initializing
it. When using custom allocators with non-zeroed buffers, unset vtable
field entries would contain garbage instead of zero (which indicates
"use default value").
This fix explicitly zeros the vtable memory after reserving space,
matching the C++ implementation's buf_.fill_big() behavior.
Added regression test using a garbage-filled allocator (0xAA) that
verifies vtable entries for unset fields are properly zeroed.
Fixes#8894

* fix for https://github.com/google/flatbuffers/issues/8759
__vector_as_array<T> calling ByteBuffer.ToArray<T> with the length in bytes by multiplying len with ByteBuffer.Sizeof<T> and FlatBuffersExampleTests extended to call GetVectorOfLongsArray/GetVectorOfDoublesArray which failed without the fix
* first try to repair build-dotnet-windows
* syntax error fixed
* Update solution creation command in build workflow
add --format sln to the dotnet new command, maybe it is currently creating a .slnx instead?

Add missing bounds checking to ByteVector before slice
operations in the Go FlatBuffers implementation. Relative offset and
vector length are now checked against the buffer size. Instead of
panicking, the code now returns nil. Regression test added.

* add deser support for enum type
* update generated files
* remove deser generator when bitflag enable
* add deser test
* Restore the Rust editions version
* Remove unnecessary modifications
* Fixes checks for serde features in flexbuffers crate
* Removes unused MapReaderIndexer use statement
* Fixes warning about nightly cfg usage
Enabling a cfg attribute through cargo::rustc-cfg in build.rs should be coupled with a cargo::rust-check-cfg value so that the compiler knows about the custom cfg. See: https://doc.rust-lang.org/rustc/check-cfg/cargo-specifics.html#cargorustc-check-cfg-for-buildrsbuild-script.
* Migrates usage of deprecated float constants
This update fixes a compiler warning from use of the old constants.
Constants like EPSILON are now directly on the float primitives (e.g. f32::EPSILON) rather than in the f32 module (std::f32::EPSILON).
The new constants have existed since 1.43.0, which appears to be below the MSRV for the flatbuffers crate.
* Fixes incorrect key in flatbuffers Cargo.toml
The old code was using package.rust, which triggered a warning about an unused key:
warning: flatbuffers/rust/flatbuffers/Cargo.toml: unused manifest key: package.rust
The correct key for specifying MSRV is rust-version. See: https://doc.rust-lang.org/cargo/reference/rust-version.html#rust-version.

When a table's name is called `Table`, the Java bindings generated result in an error due to there being 2 Tables. This fixes the issue by fully qualifyng the flatbuffers Table import.

* [Go] Write required string fields into the buffer when using Object API
In C++, CreateX allows to write the default "" value of a required
string, when the string is not explicitly set. Object API Pack method
uses this implementation of CreateX.
However, in go, despite whether the field is optional or required, it is
always checked against empty string allowing to create messages that
fail to pass the verifier. This commits partially reverts #7719 when the
string field is required.
* Add test for serializing required string fields using Object API
* Update generated code
The Monster schema contains a key string field. For historical
convenience reasons, string keys are assumed required.
* fix CScript string.compare
Because the default compare sorting rules of c# string are different from those of cpp, the binary file exported by flatc -b cannot use LookupByKey
* run generate_code.py

* Fixes to make SizeVerifier work.
In particular change all the places in the Flatbuffers library
and generated code that were using `Verifier` to instead use
`VerifierTemplate<TrackBufferSize>` and wrap them all inside
`template <bool TrackBufferSize = false>`.
Also add unit tests for SizeVerifier.
* Format using `sh scripts/clang-format-git.sh`
* Use `B` rather than `TrackBufferSize` for the name of the template parameter.
* Update generated files.
Implements InlineArrays which allow us to use Flatbuffers arrays within
Structs natively, and also implements FlatbufferVectors as a secondary API
when using mutable Structs
Fixes mutations within fixed sizes arrays
Adds tests and remove inout and mutating from generated objects in favor of borrowing

* Support native_type for tables when using the C++ object API.
If native_type is specified on a table:
- No object API struct type is generated.
- The object API refers to the table by its native_type.
- UnPack and Create<TableName> methods are declared but not defined; as they
must be user-provided.
* Add tests for native_type on tables.
* Add documentation for native_type on tables.
Per the definition of --gen-compare: only generate comparators for object API
generated structs. Types annoated with native_type must define their own
comparators if `--gen-compare` is enabled.
Also enables --gen-compare for native_type_test and fixes the test by adding a
comparator for the Native::Vector3D type.
* Implements FlatbuffersVector in swift
Implements FlatbuffersVector which confirms to RandomAccessCollection,
this would give us semi-native sugary syntax to all the arrays in swift port.
This work will also be the foundation of using arrays in swift
* Fix failing tests for Swift
Previously: X::Pack forwarded to CreateX.
Now: CreateX will forward to X::Pack.
This is a step toward enabling using native types for tables when using the
object API. When defining a native table, the user will be able to define a
custom X::Pack method (which is more consistent with the existing native_type
functionality for structs). By reversing the order of the dependencies, CreateX
can continue to be auto-generated and will use the custom X::Pack method when
overriden for native_type tables.
* Correction of bug inside ToArray<T> methods
Avoid allocating too large buffers (len is expressed in bytes, not in Ts).
Added validation to ensure len is a multiple of SizeOf<T>() before converting to array.
* Update ByteBuffer.cs
* Refactor ToArray and ToArrayPadded methods
I understand from failed test that pos, len, padLeft and padRight are expressed in Ts
* Refactor ToArray and ToArrayPadded methods
* Final correction
All functions parameters expressed in bytes for homogeneity
Tests run:
- UNSAFE_BYTEBUFFER=true/ENABLE_SPAN_T=true: passed
- UNSAFE_BYTEBUFFER=true/ENABLE_SPAN_T=false: passed
- UNSAFE_BYTEBUFFER=false/ENABLE_SPAN_T=false: passed
- UNSAFE_BYTEBUFFER=false/ENABLE_SPAN_T=true: configuration forbidden by compilation
Correction of FlatBuffers.Test.csproj to allow UNSAFE_BYTEBUFFER/ENABLE_SPAN_T tests
Correction of FlatBuffersExampleTests.cs: I think the test was not run because it could not pass (to be reviewed carefully)
