* Add fallible try_* API for FlatBufferBuilder
This is to support error propagation from Allocator trait. The Allocator
grow_downwards() method returns Result<(), Self::Error>, but
FlatBufferBuilder panics via .expect() when allocation fails instead of
propagating the error.
* Add rust fallible API docs
* 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.
* 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
