Enum ConvertIntent 

#[non_exhaustive]
pub enum ConvertIntent {
    Fastest,
    LinearLight,
    Blend,
    Perceptual,
}

What the consumer plans to do with the converted pixels.

Shifts the format negotiation cost model to prefer formats suited for the intended operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fastest

Minimize conversion effort. Good for encoding — the codec already knows what it wants, just get there cheaply.

LinearLight

Pixel-accurate operations that need linear light: resize, blur, anti-aliasing, mipmap generation. Prefers f32 Linear. Straight alpha is fine.

Blend

Compositing and blending (Porter-Duff, layer merge). Prefers f32 Linear with Premultiplied alpha.

Perceptual

Perceptual adjustments: sharpening, contrast, saturation. Prefers sRGB space (perceptually uniform).

Trait Implementations

impl Clone for ConvertIntent

fn clone(&self) -> ConvertIntent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConvertIntent

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

Formats the value using the given formatter.

impl Default for ConvertIntent

fn default() -> ConvertIntent

Returns the “default value” for a type.

impl PartialEq for ConvertIntent

fn eq(&self, other: &ConvertIntent) -> 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.
