Struct Rgb

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

RGB color, with u8 components

Fields

r: u8

red

g: u8

green

b: u8

blue

Implementations

impl Rgb

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

Create a new RGB color from its components

pub const fn is_grey(self) -> bool

pub fn nearest_ansi_in_range(self, min: u8, max: u8) -> AnsiColor

pub fn to_ansi(self) -> AnsiColor

Return the nearest ANSI color

The ansi->rgb->ansi round trip is guaranteed to always fall on the first color.

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

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>(self, other: O) -> f32

where O: Into<Rgb>,

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)

Trait Implementations

impl Clone for Rgb

fn clone(&self) -> Rgb

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rgb

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

Formats the value using the given formatter.

impl From<(f32, f32, f32)> for Rgb

fn from(c: (f32, f32, f32)) -> Rgb

Convert from a (r,g,b) float tupples with components in [0,1[

impl From<Rgb> for Color

fn from(rgb: Rgb) -> Color

Converts to this type from the input type.

impl From<Rgb> for Hsl

fn from(rgb: Rgb) -> Hsl

Converts to this type from the input type.

impl PartialEq for Rgb

fn eq(&self, other: &Rgb) -> 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.
