Struct Hsl

pub struct Hsl {
    pub h: f32,
    pub s: f32,
    pub l: f32,
}

HSL color

Fields

h: f32

hue in [0,360[

s: f32

saturation in [0,1]

l: f32

luminosity in [0,1]

Implementations

impl Hsl

pub fn new(h: f32, s: f32, l: f32) -> Hsl

Create a new HSL color from its components

pub fn checked(h: f32, s: f32, l: f32) -> Result<Hsl, CoolorError>

Create a new HSL color from its components, checking the ranges

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

pub fn to_ansi(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_rgb(self) -> Rgb

pub fn delta_h(self, other: Hsl) -> f32

pub fn delta_s(self, other: Hsl) -> f32

pub fn delta_l(self, other: Hsl) -> f32

pub fn distance_to<H>(self, other: H) -> f32

where H: Into<Hsl>,

tentatively perceptual distance between the two colors, except it’s just as unscientific it can possibly be so check it looks good before trying ot use it, at least…

pub fn near(self, other: Hsl) -> bool

Tell whether it’s about the same color

There’s no theory behind this function, it should not be used outside of unit tests

Trait Implementations

impl Clone for Hsl

fn clone(&self) -> Hsl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hsl

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

Formats the value using the given formatter.

impl From<AnsiColor> for Hsl

fn from(ansi: AnsiColor) -> Hsl

Converts to this type from the input type.

impl From<Hsl> for Color

fn from(rgb: Hsl) -> 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 Hsl

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

impl Copy for Hsl

impl StructuralPartialEq for Hsl
