What is Flatbuffers?

FlatBuffers is an efficient cross-platform serialization library for C++, C#, C, Go, Java, Kotlin, JavaScript, Lobster, Lua, TypeScript, PHP, Python, and Rust. It is primarily used for game development and other performance-critical applications. Unlike other serialization formats like Protocol Buffers, FlatBuffers does not require a parsing/unpacking step to access serialized data. Instead, it stores data in a raw buffer that can be directly accessed without further processing, leading to significant performance gains, especially in latency-sensitive scenarios.
