+ "This package provides a fast serialization and validation library, with builtin
+support for JSON, MessagePack, YAML, and TOML. It includes the following features:
+@itemize
+@item high performance encoders/decoders for common protocols.
+@item support for a wide variety of Python types. Additional types may be
+supported through extensions.
+@item zero-cost schema validation using familiar Python type annotations. In
+benchmarks msgspec decodes and validates JSON about 2x faster than @code{orjson}
+can decode it alone.
+@item a speedy Struct type for representing structured data.
