Struct Rgb 

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

An sRGB color. Hex round-trips losslessly.

Fields

r: u8

g: u8

b: u8

Implementations

impl Rgb

pub fn from_hex(s: &str) -> Option<Rgb>

Parse #rgb or #rrggbb (case-insensitive). Returns None otherwise.

pub fn to_hex(self) -> String

Lowercase #rrggbb.

pub fn tuple(self) -> (u8, u8, u8)

impl Rgb

pub fn to_oklab(self) -> Oklab

Convert to OKLab (Ottosson’s sRGB matrices).

The matrix coefficients are quoted at their published precision so they can be diffed against the reference. f32 rounds them at compile time; truncating the literals would only make them harder to check.

pub fn from_oklab(c: Oklab) -> Rgb

Convert from OKLab back to the nearest in-gamut sRGB.

Published precision, as in Rgb::to_oklab.
