1//! This library provides types and functions which are used by the Rust code generated by
2//! [`naga_rust_back`] or [`naga_rust_embed`]. These types and functions implement vector arithmetic
3//! in the style expected by shader code, which differs from straightforward Rust in various ways.
4//!
5//! This library currently does not have a clean public API distinct from the API provided
6//! for the benefit of the code generator. Expect changes in future versions.
