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.

Commit

SetRegion

Fields

region: Option<WlRegion>

SetContrast

Fields

contrast: f64

SetIntensity

Fields

intensity: f64

SetSaturation

Fields

saturation: f64

Release

release the contrast object

This is a destructor, once received this object cannot be used any longer.

SetFrost

opt into frost effect w/ given colour

enables ‘frost’ variant of contrast effect.

‘frost’ is an enhanced version of the contrast effect that uses different colour arithmetic to get backgrounds simultaneously higher in contrast and (apparent) transparency.

r, g, b, a are channels from 0-255, indicating a colour to use in contrast calculation. should be based off of the “main” background colour of the surface.

Only available since version 2 of the interface

Fields

red: i32

green: i32

blue: i32

alpha: i32

UnsetFrost

opts out of frost effect

Only available since version 2 of the interface
