Implementations

impl Ansi256Color

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

Construct color info from ANSI-256 index.

Examples

use approx::assert_abs_diff_eq;
use palette::Srgb;

let color = Ansi256Color::new(208, 255, 135, 0);

assert_eq!(color.index, 208);
assert_eq!(color.srgb, Srgb::new(255u8, 135, 0));

// cross-check with https://ajalt.github.io/colormath/converter/
// sRGB (0-255) 255, 135, 0
// Oklab 0.74264, 0.10158, 0.15067
// Oklch 0.74264, 0.18171, 56.01118

Trait Implementations

impl Clone for Ansi256Color

fn clone(&self) -> Ansi256Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ansi256Color

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

Formats the value using the given formatter.

impl Display for Ansi256Color

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

Formats the value using the given formatter.

impl Gray for Ansi256Color

fn is_gray(&self) -> bool

impl PartialEq for Ansi256Color

fn eq(&self, other: &Ansi256Color) -> bool

This method tests for self and other values to be equal, and is used by ==.

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.
