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.

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

UnsetFrost

opts out of frost effect
