Struct coolor::Rgb

impl Rgb

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

Create a new RGB color from its components

pub const fn is_grey(self) -> bool

pub fn to_ansi_slow(self) -> AnsiColor

Return the nearest ANSI color

This is a slow function as it literally tries all ANSI colors and picks the nearest one.

pub fn to_ansi(self) -> AnsiColor

Return the nearest ANSI color

This uses the excellent ansi_colours crate, as it’s very fast and gives rather good conversions

pub fn mix(c1: Self, w1: f32, c2: Self, w2: f32) -> Self

pub fn to_hsl(self) -> Hsl

pub fn rp(self) -> f32

red part in [0,1]

pub fn gp(self) -> f32

green part in [0,1]

pub fn bp(self) -> f32

blue part in [0,1]

pub fn parts(self) -> (f32, f32, f32)

pub fn luma(self) -> f32

Compute the Luma value characterizing the “light” of the color, going from 0 (black) to 1 (white).

pub fn distance_to<O: Into<Rgb>>(self, other: O) -> f32

tentatively perceptual distance between two RGB colors (adapted from the ansi_colours crate, by mina86, who adapted a formula found at https://www.compuphase.com/cmetric.htm)

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

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