Struct RayonReversibleDwt53Accelerator 

pub struct RayonReversibleDwt53Accelerator { /* private fields */ }

CPU/Rayon accelerator for the exact reversible integer 5/3 first level.

This backend keeps j2k’s scalar ISLOW IDCT semantics as the oracle: each 8x8 block is decoded with j2k-jpeg, level-shifted to signed component samples, then transformed with reversible integer 5/3 lifting.
