It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility. Quick Start ----------- [](#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](https://flatbuffers.dev/flatbuffers_guide_writing_schema.html) to define the data you want to serialize. See [monster.fbs](https://github.com/google/flatbuffers/blob/master/samples/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](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.cpp#L24-L56)) 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](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.rs#L92-L106) reading the data written by `C++`.
