Struct Rgba 

pub struct Rgba {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

RGBA color with sRGB-style channels conventionally stored in the 0.0..=1.0 range.

Fields

r: f32

g: f32

b: f32

a: f32

Implementations

impl Rgba

pub const BLACK: Self

pub const WHITE: Self

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

pub const fn rgb8(r: u8, g: u8, b: u8) -> Self

pub const fn rgba8(r: u8, g: u8, b: u8, a: u8) -> Self

pub fn with_alpha(self, alpha: f32) -> Self

pub fn mix(self, other: Self, amount: f32) -> Self

pub fn sanitized(self) -> Self

pub fn relative_luminance(self) -> f32

Returns WCAG relative luminance, clamping non-finite or out-of-range color channels.

pub fn contrast_ratio(self, other: Self) -> f32

Returns the WCAG contrast ratio between two colors.

pub fn readable_text_color(self) -> Self

Chooses black or white text, whichever has higher contrast on this color.

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

Trait Implementations

impl Clone for Rgba

fn clone(&self) -> Rgba

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rgba

impl Debug for Rgba

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Rgba

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Rgba

fn eq(&self, other: &Rgba) -> 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 Serialize for Rgba

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
