Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
}

An opaque 24-bit color.

Fields

r: u8

g: u8

b: u8

Implementations

impl Color

pub const fn new(r: u8, g: u8, b: u8) -> Self

pub const fn hex(s: &str) -> Self

Parse a #rrggbb / rrggbb / #rgb / rgb hex string.

Panics on malformed input — callers pass static palette literals, so a bad value is a programming error that should fail loudly at startup.

pub fn from_hsla(c: Hsla) -> Color

Build an opaque Color from a gpui Hsla, dropping any alpha. Used so a CSS color (which parses to Hsla) can populate the opaque theme fields.

pub fn rgba(self) -> Rgba

As an opaque gpui Rgba.

pub fn hsla(self) -> Hsla

As an opaque gpui Hsla.

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

As a gpui Hsla with the given alpha in 0.0..=1.0.

pub fn luminance(self) -> f32

Relative luminance in 0.0..=1.0 (Rec. 709 weights). Used to pick a readable foreground (black vs. white) over a filled color.

pub fn contrasting(self) -> Color

A foreground color (black or white) with adequate contrast over self.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Color

impl Debug for Color

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Color

impl From<Color> for Hsla

fn from(c: Color) -> Hsla

Converts to this type from the input type.

impl Hash for Color

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
