3//! NVIDIA CUDA GPU device-output adapter for Rust JPEG 2000 / HTJ2K in `j2k`.
4//!
5//! This crate intentionally exposes the same backend-selection surface as the
6//! Metal adapter. CPU and auto requests return host-backed surfaces. Strict
7//! CUDA requests are reserved for CUDA-resident HTJ2K codestream decode and
8//! CUDA-resident HTJ2K encode inputs; the CPU-decode-then-upload path is
9//! exposed through explicit CPU-staged APIs.
