Enum DecodeRequest 

#[non_exhaustive]
pub enum DecodeRequest {
    Full,
    Region {
        roi: Rect,
    },
    Reduced {
        scale: Downscale,
    },

Requested pixels from one encoded image.

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.

Full

Decode the complete image at its native resolution.

Region

Decode a full-resolution source region.

Fields

roi: Rect

Source-coordinate region of interest.

Reduced

Decode the complete image at a reduced resolution.

Fields

scale: Downscale

Power-of-two reduction.

RegionReduced

Decode a source region at a reduced resolution.

Fields

roi: Rect

Source-coordinate region of interest.

scale: Downscale

Power-of-two reduction.
