[0.2.0]

Added

  • New affn-derive proc-macro crate providing #[derive(ReferenceFrame)] and #[derive(ReferenceCenter)] (re-exported via affn::prelude).
  • ops module with domain-agnostic affine operators: Rotation3, Translation3, and Isometry3.
  • Cartesian line-of-sight helpers: line_of_sight, line_of_sight_with_distance, and try_line_of_sight.
  • Cartesian ↔ spherical conversions for positions/directions (to_spherical, from_spherical), plus roundtrip example.
  • More examples under examples/ (basic cartesian algebra, parameterized centers, spherical roundtrip).
  • GitHub Actions CI (check, fmt, clippy, test, doctest, coverage) and a local runner script (ci-local.sh).
  • Integration tests for derive macros and expanded unit tests for cartesian/spherical types and formatting.

Changed

  • Crate is now fully domain-agnostic: concrete frames/centers are expected to live in downstream crates.
  • ReferenceCenter and ReferenceFrame now require Copy + Clone + Debug; center runtime parameters are carried via ReferenceCenter::Params.
  • Position<C, F, U> stores C::Params inline and adds new_with_params (plus convenience new for Params = () centers).
  • Public API reorganized with crate-level re-exports and a prelude for common imports (types, traits, derives, and operators).
  • Version bumped from 0.1.0 to 0.2.0 and Cargo.lock updated to include affn-derive.

Deprecated

Removed

  • Predefined astronomy-specific frames and centers (e.g., ICRS, Ecliptic, Heliocentric, Geocentric, Topocentric) from the core crate.
  • ObserverSite and related astronomy-specific center parameter types from the core crate.

Fixed

  • Small performance improvements in affine operator hot paths (e.g., negation and loop-level optimizations).
