Implementations

impl Color

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

Returns a color value from red, green, blue char values. Alpha will be set to 255.

pub const fn rgbf(r: f32, g: f32, b: f32) -> Self

Returns a color value from red, green, blue float values. Alpha will be set to 1.0.

pub fn rgba(r: u8, g: u8, b: u8, a: u8) -> Self

Returns a color value from red, green, blue and alpha char values.

pub const fn rgbaf(r: f32, g: f32, b: f32, a: f32) -> Self

Returns a color value from red, green, blue and alpha char values.

pub fn hsl(h: f32, s: f32, l: f32) -> Self

Returns color value specified by hue, saturation and lightness. HSL values are all in range [0..1], alpha will be set to 1.0.

pub fn hsla(h: f32, s: f32, l: f32, a: f32) -> Self

Returns color value specified by hue, saturation, lightness and alpha. All values are in range [0..1]

pub fn hex(raw_hex: &str) -> Self

Returns color value for a 6-digit (RRGGBB) or 8-digit (RRGGBBAA) HTML hexadecimal string. Any other length produces rgb(0,0,0). The “#” is optional.

pub const fn white() -> Self

Returns a white color

pub const fn black() -> Self

Returns a black color

pub fn set_alpha(&mut self, a: u8)

Sets transparency of a color value.

pub fn set_alphaf(&mut self, a: f32)

Sets transparency of a color value.

pub fn premultiplied(self) -> Self

pub const fn to_array(self) -> [f32; 4]

pub fn is_black(&self) -> bool

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Color

fn eq(&self, other: &Color) -> 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 Color

fn partial_cmp(&self, other: &Color) -> 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.
