Enum ComputeBackend 

pub enum ComputeBackend {
    Auto,
    Cpu,
    G2d,
    OpenGl,
}

Compute backend selection for ImageProcessor.

Use with ImageProcessorConfig::backend to select which backend the processor should prefer. When a specific backend is selected, the processor initializes that backend plus CPU as a fallback. When Auto is used, the existing environment-variable-driven selection applies.

Variants

Auto

Auto-detect based on available hardware and environment variables.

Cpu

CPU-only processing (no hardware acceleration).

G2d

Prefer G2D hardware blitter (+ CPU fallback).

OpenGl

Prefer OpenGL ES (+ CPU fallback).

Trait Implementations

impl Clone for ComputeBackend

fn clone(&self) -> ComputeBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComputeBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ComputeBackend

fn default() -> ComputeBackend

Returns the “default value” for a type.

impl PartialEq for ComputeBackend

fn eq(&self, other: &ComputeBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for ComputeBackend

impl Eq for ComputeBackend

impl StructuralPartialEq for ComputeBackend
