Struct Rgba 

#[repr(C)]
pub struct Rgba {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

An RGBA color

Fields

r: f32

The red component of the color, in the range 0.0 to 1.0

g: f32

The green component of the color, in the range 0.0 to 1.0

b: f32

The blue component of the color, in the range 0.0 to 1.0

a: f32

The alpha component of the color, in the range 0.0 to 1.0

Implementations

impl Rgba

pub fn blend(&self, other: Rgba) -> Self

Create a new Rgba color by blending this and another color together

pub fn alpha(&self, a: f32) -> Self

Returns a new RGBA color with the same red, green and blue channels, but with a new alpha value.

Example:

use gpui::rgba;
let color = rgba(0xFF0000FF);
let faded = color.alpha(0.25);
assert_eq!(faded.a, 0.25);

This will return a red color with 25% opacity.

Example:

use gpui::rgba;
let color = rgba(0x3399FFCC);
let transparent = color.alpha(0.0);
assert_eq!(transparent.a, 0.0);

This will return the same blue color, fully transparent.

pub fn opacity(&self, factor: f32) -> Self

Returns a new RGBA color with the same red, green, and blue channels, but with the alpha channel multiplied by the given factor.

Example:

use gpui::rgba;
let color = rgba(0xFF0000FF); // Fully opaque red
let faded = color.opacity(0.5);
assert_eq!(faded.a, 0.5);

This will return a red color with 50% opacity.

Example:

use gpui::rgba;
let color = rgba(0x3399FFCC); // A light blue with 80% opacity
let faded = color.opacity(0.5);
assert!((faded.a - 0.4).abs() < 1e-6);

This will return the same blue color scaled down to 40% opacity.
