Struct cosmic::cosmic_theme::palette::RgbHue

#[repr(C)]
pub struct RgbHue<T = f32>(/* private fields */);

A hue type for the RGB family of color spaces.

It’s measured in degrees and uses the three additive primaries red, green and blue.

The hue is a circular type, where 0 and 360 is the same, and it’s normalized to (-180, 180] when it’s converted to a linear number (like f32). This makes many calculations easier, but may also have some surprising effects if it’s expected to act as a linear number.

Implementations

impl<T> RgbHue<T>

pub const fn new(angle: T) -> RgbHue<T>

Create a new hue, specified in the default unit for the angle type T.

f32, f64 and other real number types represent degrees, while u8 simply represents the range [0, 360] as [0, 256].

pub fn into_inner(self) -> T

Get the internal representation without normalizing or converting it.

f32, f64 and other real number types represent degrees, while u8 simply represents the range [0, 360] as [0, 256].

They will have to be multiplied by a radius values, such as saturation, value, chroma, etc., to represent a specific color.
