Enum EncodeBackendPreference 

pub enum EncodeBackendPreference {
    Auto,
    CpuOnly,
    RequireDevice,
}

Backend preference for JPEG 2000 lossless encoding.

Variants

Auto

Pick the fastest safe backend exposed by the caller.

An accelerator may decline an unavailable or unsupported stage and let the CPU complete the request. Accelerator execution errors are returned instead of silently retrying the entire encode on the CPU.

CpuOnly

Require the pure Rust CPU encoder.

RequireDevice

Require a device encoder and fail if unavailable or unsupported.
