metar_taf_parser

⚠️ Status: Active development – current version 0.2.19

A modern, strongly-typed METAR and TAF parser library written in Rust.

This project is now focused on the single library crate (metar-taf-parser) and is a Rust port of the original Python project: https://github.com/mivek/python-metar-taf-parser

Porting and parity work also tracks the maintained fork: https://github.com/umpire274/python-metar-taf-parser.

✈️ Goals

Provide a robust Rust-native API for METAR/TAF parsing.
Reach feature parity with the referenced Python fork.
Keep the public API ergonomic and strongly typed for embedding in other apps.
During porting, parser groups are being migrated using the same regex-first approach used in the Python fork to preserve behavior.
Porting process follows a regex-alignment policy documented in docs/PORTING_REGEX_POLICY.md.

The repository now exposes a single library crate at the root:

metar_taf_parser/
├── src/
├── tests/
├── resources/
├── Cargo.toml
├── README.md
└── CHANGELOG.md

Add the core crate to your Cargo.toml:

[dependencies]

metar-taf-parser = "0.2.19"

Example:

use metar_taf_parser::parse_metar;

let metar = parse_metar(
    "LIRF 121250Z 18012KT 9999 FEW030 SCT080 18/12 Q1015"
)?;

println!("{:#?}", metar);

For strict parsing (error on unsupported groups), use parse_taf_strict.
