It provides high-performance encoders and decoders for JSON, MessagePack, YAML, and TOML, combined with zero-cost schema validation using standard Python type annotations. The library includes a Struct type for representing structured data with performance characteristics significantly faster than dataclasses or attrs for common operations.\n\nThe package is designed to handle the full serialization and validation workflow: you define schemas using type annotations, encode messages to one of the supported protocols, and decode them back with optional schema validation. It has no runtime dependencies and is intended as a drop-in replacement for slower serialization libraries when performance matters. However, the fork explicitly accepts only minimal maintenance and packaging updates, not new features.","worth_installing":"Yes, if you need fast serialization with schema validation and accept the trade-off of a community fork in maintenance mode. The package offers genuine performance gains and is well-suited for latency-sensitive services, data pipelines, and API layers. However, be aware that it receives only minimal maintenance and packaging updates\u2014not new features\u2014so evaluate whether upstream msgspec or the original fork better fits your long-term needs."},"id":"msgspec-m","links":{"html":"https://skillfed.io/packages/msgspec-m","md":"https://skillfed.io/packages/msgspec-m.md","pypi":"https://pypi.org/project/msgspec-m/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-11-14","license_spdx":null,"license_treatment":"permissive","name":"msgspec-m","python_support":"supports_current","summary":"A fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML."},"popularity":{"monthly_downloads":74779,"position":14794,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.19.3"}
