Improve error handling on Object API name collision. (#8275)
If a schema contains a message named e.g. FooT and a message named Foo
while the Object API suffix is T, then two classes with colliding names
will be generated. This scenario will produce a C++ compiler error, but
it's confusing.

This patch moves the error to the compiler, allowing the user to more
readily act to correct the issue.

FlatBuffers is a cross platform serialization library architected for maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.

Quick Start

  1. Build the compiler for flatbuffers (flatc)

    Use cmake to create the build files for your platform and then perform the compliation (Linux example).

    cmake -G "Unix Makefiles"
    make -j
    
  2. Define your flatbuffer schema (.fbs)

    Write the schema to define the data you want to serialize. See monster.fbs for an example.

  3. Generate code for your language(s)

    Use the flatc compiler to take your schema and generate language-specific code:

    ./flatc --cpp --rust monster.fbs
    

    Which generates monster_generated.h and monster_generated.rs files.

  4. Serialize data

    Use the generated code, as well as the FlatBufferBuilder to construct your serialized buffer. (C++ example)

  5. Transmit/store/save Buffer

    Use your serialized buffer however you want. Send it to someone, save it for later, etc...

  6. Read the data

    Use the generated accessors to read the data from the serialized buffer.

    It doesn't need to be the same language/schema version, FlatBuffers ensures the data is readable across languages and schema versions. See the Rust example reading the data written by C++.
