Struct Color

pub struct Color {
    pub red: u16,
    pub green: u16,
    pub blue: u16,
    pub alpha: u16,
}

An RGB color with 16 bits per channel and an optional alpha channel.

Fields

red: u16

Red

green: u16

Green

blue: u16

Blue

alpha: u16

Alpha.

Can almost always be ignored as it is rarely set to something other than the default (0xffff).

Implementations

impl Color

pub const fn rgb(red: u16, green: u16, blue: u16) -> Self

Construct a new Color from (r, g, b) components, with the default alpha (0xffff).

pub fn parse(input: &[u8]) -> Result<Color, ColorParseError>

Parses the subset of X11 Color Strings emitted by terminals in response to OSC color queries (OSC 10, OSC 11, …).

This function is a rough analogue to XParseColor.

Accepted Formats

• #<red><green><blue>
• rgb:<red>/<green>/<blue>
• rgba:<red>/<green>/<blue>/<alpha> (rxvt-unicode extension)

where <red>, <green> and <blue> are hexadecimal numbers with 1-4 digits.

impl Color

pub fn perceived_lightness(&self) -> f32

Perceptual lightness (L*) as a value between 0.0 (black) and 1.0 (white) where 0.5 is the perceptual middle gray.

Note that the color’s alpha is ignored.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

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.
