abnf-rust

Rust-backed parser engine for the abnf package.

This is a companion distribution: install it via

pip install abnf[rust]

The package supplies the importable Python module abnf_rust, a compiled extension built with PyO3 that accelerates the combinator engine in abnf.parser. When abnf_rust is importable, abnf.parser automatically routes its combinator primitives through this module; the pure-Python implementation in abnf._parser_python remains available as a fallback and as the reference for behavior parity.

To force the pure-Python backend even when abnf-rust is installed, set the environment variable ABNF_NO_RUST=1.

Layout

  • rust/core/ — pure-Rust parser engine (no Python dependency).
  • rust/pyo3/ — PyO3 bindings, compiled to abnf_rust._ext.
  • src/abnf_rust/ — Python wrapper package that re-exports the compiled symbols.
