devel/py-msgspec 0.21.1 NetBSD

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.
