Description
Transit.c is an addition to the set of libraries to support transit data interchange format written in C11. It supports full 0.8 specification of cognitect's transit-format: JSON, JSON-Verbose and MessagePack encodings, all ground and extension types, compression via keys caching, extensibility via custom tag handlers.

Could you build this?
No Writing a spec-compliant, zero-dependency serialization and deserialization library in C11 for Cognitect's Transit format (handling JSON and MessagePack with cache tables) requires specialized low-level systems programming.
What it would actually take: The implementation demands strict C11 code parsing streaming JSON and MessagePack encodings, implementing Transit's dynamic LRU string cache, and handling custom extension tags with zero-allocation or strict buffer management. It requires deep expertise in memory layouts, pointer arithmetic, binary data decoding, and rigorous fuzz testing against format edge cases.
