Every protocol follows a consistent six-file pattern: frozen header dataclass, base composition layer, three-phase RX parser pipeline, keyword-only TX assembler, and a two-axis error tree (IntegrityError for structural/wire-shape issues, SanityError for logical invariants).\n\nThe library is designed for strict, wire-hostile input handling: validation errors are typed exceptions that survive Python's -O optimization flag (unlike asserts), so they defend against malformed network data. Unknown wire codepoints are materialized as identity-stable pseudo-members via stdlib enum hooks, with no third-party enum library needed. It ships with py.typed and is strict-mypy clean, making it suitable for type-safe network protocol work in applications that need RFC-compliant, deterministic packet handling.","worth_installing":"Yes, if you need RFC-grounded network protocol parsing and assembly with strict validation. The package is actively maintained, has no known vulnerabilities, low install friction, and comprehensive protocol coverage. The GPL-3.0-or-later license is a blocker only for proprietary closed-source work. Verify the Python version requirement before committing to production."},"id":"pmd-net-proto","links":{"html":"https://skillfed.io/packages/pmd-net-proto","md":"https://skillfed.io/packages/pmd-net-proto.md","pypi":"https://pypi.org/project/pmd-net-proto/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-22","license_spdx":"GPL-3.0-or-later","license_treatment":"copyleft","name":"pmd-net-proto","python_support":"supports_current","summary":"The network-protocol packet parse/assemble layer of the PyTCP stack \u2014 Ethernet through TCP/UDP \u2014 fully usable on its own."},"popularity":{"monthly_downloads":100759,"position":12974,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.0.3"}
