j2k_codec_math/lib.rs
1//! Shared codec constants, generated fragments, and helper algorithms for the
2//! `j2k` workspace.
3//!
4//! This crate is deliberately small, allocation-free, and `no_std`. Its
5//! constants and pure helper algorithms must stay equivalent across CPU,
6//! CUDA-Oxide, and Metal backends, but it does not own backend dispatch or
7//! kernel-launch policy.
