msgspec is a fast serialization and validation library, with builtin
support for JSON, MessagePack, YAML, and TOML. It features:

* High performance encoders/decoders for common protocols. The JSON
  and MessagePack implementations regularly benchmark as the fastest
  options for Python.

* Support for a wide variety of Python types. Additional types may
  be supported through extensions.

* Zero-cost schema validation using familiar Python type annotations.
  In benchmarks msgspec decodes and validates JSON faster than orjson
  can decode it alone.

* A speedy Struct type for representing structured data. If you
  already use dataclasses or attrs, Structs should feel familiar.
  However, they're 5-60x faster for common operations.
