oxiproj-core 0.1.2

#![forbid(unsafe_code)]
#![warn(missing_docs)]
// The `gpu` feature requires `std` (CUDA driver, threads, `HashMap`). If both
// `gpu` and `no_std` are requested at once (e.g. `cargo build --all-features`),
// `std` wins so the GPU module can compile — a no_std target can't drive a GPU
// anyway. The `#[cfg(feature = "no_std")]` import shims elsewhere stay valid
// because their `alloc`/`core`/`libm` paths also resolve under `std`.
#![cfg_attr(all(feature = "no_std", not(feature = "gpu")), no_std)]
//! `oxiproj-core` — Foundation types: coordinates, errors, ellipsoids, datums, and units.
//!
//! Part of [OxiProj](https://github.com/cool-japan/oxiproj), the COOLJAPAN Pure-Rust
//! port of PROJ. See the workspace blueprint `oxiproj.md` for the full design.
