Struct rsass::value::Hwba

pub struct Hwba { /* private fields */ }

A color defined by hue, whiteness, blackness, and alpha.

All components are rational numbers. The hue is in degrees (0..360). The whiteness, blackness, and alpha are all in the zero to one range (inclusive), whith the additional invariant that whiteness + blackness will never be more than one.

Implementations

impl Hwba

pub fn new(hue: Rational, w: Rational, b: Rational, alpha: Rational) -> Self

Create a new hwba color value.

Hue is modulo 360 degrees. Other inputs will be clamped to their ranges.

pub fn hue(&self) -> Rational

Get the hue of this color.

pub fn whiteness(&self) -> Rational

Get the whiteness of this color.

Zero is no whiteness, one means this color is white.

pub fn blackness(&self) -> Rational

Get the black of this color.

Zero is no blackness, one means this color is black.

pub fn alpha(&self) -> Rational

Get the alpha value of this color.

Zero is fully transparent, one is fully opaque.

pub fn set_alpha(&mut self, alpha: Rational)

Set the alpha value of this color.

Zero is fully transparent, one is fully opaque.

Trait Implementations

impl Clone for Hwba

fn clone(&self) -> Hwba

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hwba

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

Formats the value using the given formatter.

impl From<&Hsla> for Hwba

fn from(hsla: &Hsla) -> Self

Converts to this type from the input type.

impl From<&Hwba> for Hsla

fn from(hwba: &Hwba) -> Self

Converts to this type from the input type.

impl From<&Hwba> for Rgba

fn from(hwba: &Hwba) -> Self

Converts to this type from the input type.

impl From<&Rgba> for Hwba

fn from(rgba: &Rgba) -> Self

Converts to this type from the input type.

impl From<Hwba> for Color

fn from(hwba: Hwba) -> Self

Converts to this type from the input type.

impl Ord for Hwba

fn cmp(&self, other: &Hwba) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Hwba

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

impl PartialOrd for Hwba

fn partial_cmp(&self, other: &Hwba) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
