siderust-py 0.2.1

//! Python bindings for siderust astrometry and astrodynamics.
//!
//! This crate provides Python bindings for the siderust Rust library, enabling
//! observation planning, coordinate transforms, altitude/azimuth queries, and
//! ephemeris access from Python — all backed by Rust for performance.

/// siderust: Astrometry & Astrodynamics for Python
///
/// This module provides observation planning, coordinate transforms,
/// altitude/azimuth queries, and ephemeris access, powered by Rust.
///
/// Example:
/// >>> from siderust import Observer, Body
/// >>> obs = Observer.roque_de_los_muchachos()
/// >>> from tempoch import ModifiedJulianDate
/// >>> mjd = ModifiedJulianDate(60000.0)
/// >>> alt = Body.Sun.altitude_at(obs, mjd.value)
/// >>> print(f"Sun altitude: {alt:.4f} deg")
