* [Python] Use correct type for str with None
Otherwise mypy will correctly flag code like this
def __init__(self):
self.fooBar = None # type: Optional[str]
error: Incompatible types in assignment (expression has type "None", variable has type "str")
* [Python] Make list type optional as they can contain None
Fixes an issue where exports were using incorrect relative paths for
>=3 namespace levels. This is fixed by making the starting range of the
namespace components relative to the amount of components.

Adding support for windows requires the code generations
to add a compiler statement to completely ignore GRPC code
generation on windows
Cleanup the project to use the main Package.swift to run tests
instead of having it separate and includes the imports for GRPC
within it.
Adds windows swift ci
* clang-format
* [Python] Replace . with _ in grpc filename suffix
Having filenames with . like `file.fb.grcp`
is not great for Python. Since dots are used for namespaces.
Replacing all of them with _ eg suffix `foo.bar.baz` will become
`foo_bar_baz`.
Restoring the previous default `_fb` suffix.
* [Python] Use namespace in path
This fixes a regression introduced with:
fb9afbafc7
And generates the grpc file in the namespace folder again.
* Sync commandline docs with web docs
* Offical Swift port for FlexBuffers
This is the offical port for FlexBuffers within
swift, and it introcudes a Common Module where code
is shared between flatbuffers and flexbuffers.
Writing most supported values like maps, vectors,
nil and scalars into a flexbuffer buffer. And includes
tests to verify that its similar to cpp
* Reading a flexbuffer
Implementing reading from a flexbuffer, enabling
most of the buffers features, like most types, maps, vectors,
typedvectors, and fixedtypedvectors.
Currently, if an offset/object cant be read we default to a swift
nil instead of the default flexbuffers 'null' with all values.
* Fixes bazel breaking due to new project structure
Address warnings within the library
* Adds comment on why we added the code & properly enforce the amout of bytes needed
For Vector or Array of structures the dereference operator of an
iterator returns the pointer to the structure. However, IndirectHelper,
which is used in the implementation of this operator, is instantiated
in the way that the IndirectHelper::Read returns structure by value.
This is because, Vector and Array instantiate IndirectHelper with
const T*, but VectorIterator instantiates IndirectHelper with T. There
are three IndirectHelper template definition: first for T, second for
Offset<T> and the last one for const T*. Those have different
IndirectHelper:Read implementations and (more importantly) return type.
This is the reason of mismatch in VectorIterator::operator* between
return type declaration and what was exactly returned.
That is, for Array<T,...> where T is scalar the VectorIterator is
instantiated as VectorIterator<T, T>, dereference operator returns T
and its implementation uses IndirectHelper<T> which Read function
returns T.
When T is not scalar, then VectorIterator is instantiated as
VectorIterator<T, const T *>, dereference operator returns const T * and
its implementation uses IndirectHelper<T> which Read function returns T.
The fix is done as follows:
* implement type trait is_specialization_of_Offset and
is_specialization_of_Offset64,
* change partial specialization of IndirectHelper with const T * that
it is instantiated by T and enabled only if T is not scalar and not
specialization of Offset or Offset64,
* remove type differentiation (due to scalar) from Array..
The above makes the IndirectHelper able to correctly instantiate itself
basing only on T. Thus, the instantiation in VectorIterator correctly
instantiate IndirectHelper::Read function, especially the return type.
Fixes access to union members when generating code with options "--cpp-field-case-style upper" and "--gen-object-api"

* Adds new API to reduce memory copying within swift
Adds new storage container _InternalByteBuffer which
will be holding the data that will be created within the swift
lib, however reading data will be redirected to ByteBuffer, which
should be able to handle all types of data that swift provide without
the need to copy the data itself. This is due to holding a reference to
the data.
Replaces assumingMemoryBinding with bindMemory which is safer
Adds function that provides access to a UnsafeBufferPointer for
scalars and NativeStructs within swift
Updates docs
Suppress compilation warnings by replacing var with let
Using overflow operators within swift to improve performance
Adds tests for GRPC message creation from a retained _InternalByteBuffer
* flatbuffers Rust reflection: replace num with num-traits
num crate is a wrapper over num-traits and a few other crates, that
reexports the APIs from all of them. We only need num-traits.

* Fix tests build on Swift 5.8
grpc-swift 1.4.1 depends on swift-nio-ssl 2.14.0+ [1]. swift-nio-ssl 2.29.1
published on 2025-01-30, introduced some code [2] that uses a "switch
expression syntax" supported since Swift 5.9 [3]. Attempts to compile it with
Swift 5.8 cause build errors.
swift-nio-ssl project doesn't seem to support Swift 5.8. A commit from
2024-10-29 removes a "deprecated reference to a Swift 5.8 pipeline" [4].
swift-nio-ssl 2.29.0 is the last version that can be compiled with Swift
5.8. This commit pins it to that exact version.

We need to copy the .fbs files into the package used for .bfbs files.
This is necessary as flatc doesn't provide support to specify the full
output file name for an .fbs file in a different folder.
I tried OUTPUT_FILE env var but this doesn't seem to be honored by
flatc.
Transitive headers like array.h have not been available in the runtime_cc target causing the build to fail. Adding all public headers to make sure transitive headers of flatbuffers.h are available.

* #Rust Add setters for scalar fields
* #Rust Add setter for string fields
