itu-rs 1.2.1

Python bindings for selected ITU-R P-series atmospheric propagation models

itu-rs Python bindings

Python bindings for the Rust itu-rs crate.

Install from PyPI:

uv add itu-rs
# or: pip install itu-rs

Import from Python:

import itu_rs

attenuation = itu_rs.gas_attenuation_default(
    45.4215, -75.6972, 12.0, 30.0, 0.1, 1.2
)
print(attenuation)

The bindings expose the same implemented Rust APIs, including the direct P.1144, P.618, and P.676 helper functions.

The Python package downloads and caches the ITU-R model data automatically on first import. Set ITU_RS_DATA_DIR to use an existing local data directory.

For local development, use uv:

uv run --project python --group dev maturin develop --manifest-path python/Cargo.toml
uv run --project python --group dev pytest python/tests
