flatc -M: escape make-special characters in depfiles
flatc -M emits dependency rules containing filenames as-is. Characters
that are special to make ($ # : space \) are not escaped, so a schema
whose include path contains any of them produces a depfile that make or
Ninja mis-parses. GCC and Clang escape these in -M/-MD output, and glslang
does the same via writeEscapedDepString.

Add EscapeMakeDep and apply it to every active GenerateMakeRule site, and
emit the rule as a single line instead of word-wrapping (wrapping splits
escaped filenames on their spaces).

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 compilation (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++.
