Enum Discounting

#[non_exhaustive]
pub enum Discounting<T> {
    Auto,
    Custom(T),
}

The degree of discounting of (or adaptation to) the illuminant.

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.

Auto

Uses luminance levels and surround conditions to calculate the discounting, using the original CIECAM16 D function. Ranges from 0.65 to 1.0.

Custom(T)

A value between 0.0 and 1.0, where 0.0 represents no adaptation, and 1.0 represents that the observer’s vision is fully adapted to the illuminant. Values outside that range will be clamped.
