Struct Hsla 

pub struct Hsla {
    pub hue: f32,
    pub saturation: f32,
    pub lightness: f32,
    pub alpha: f32,
}

HSL + alpha.

Equality

Equality is determined using about_eq with 0.001 granularity for hue and 0.00001 granularity for the others.

Fields

hue: f32

Hue color angle in the [0.0..=360.0] range.

saturation: f32

Saturation amount in the [0.0..=1.0] range, zero is gray, one is full color.

lightness: f32

Lightness amount in the [0.0..=1.0] range, zero is black, one is white.

alpha: f32

Alpha channel in the [0.0..=1.0] range, zero is invisible, one is opaque.

Implementations

pub fn set_saturation<S>(&mut self, saturation: S)

where S: Into<Factor>,

Sets the saturation value.
