Struct HSL
Source pub struct HSL {
pub h: f32,
pub s: f32,
pub l: f32,
}
Expand description
HSL color.
| Field | Range | Description |
|---|
h | 0..360 | Hue angle (wraps at 360) |
s | 0..1 | Saturation |
l | 0..1 | Lightness |
§Why no arithmetic?
Same reasoning as HSV: hue wraparound makes naive componentwise
operations incorrect. Convert to RGBA, manipulate there, convert back.
See HSV for details and alternatives.
Construct an HSL color with clamping.
Hue is clamped to 0..360, saturation and lightness to 0..1.
Convert to RGBA with a custom alpha.
Equivalent to self.to_rgba().with_alpha(alpha).
Performs copy-assignment from
source.

Encode as a hex string: #RRGGBBAA.
Convert to 8-bit byte channels: (r, g, b, a) in 0..255.
Returns the argument unchanged.
Calls U::from(self).
That is, this conversion is whatever the implementation of
From<T> for U chooses to do.
