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

Create a new Color from four f32’s in the range [0.0-1.0]

pub fn from_rgba(r: u8, g: u8, b: u8, a: u8) -> Color

Create a new Color from four u8’s in the range [0-255]

pub fn from_rgb(r: u8, g: u8, b: u8) -> Color

Create a new Color from three u8’s in the range [0-255], with the alpha component fixed to 255 (opaque)

pub fn to_rgba(self) -> (u8, u8, u8, u8)

Return a tuple of four u8’s in the range [0-255] with the Color’s components.

pub fn to_rgb(self) -> (u8, u8, u8)

Return a tuple of three u8’s in the range [0-255] with the Color’s components.

pub fn from_rgba_u32(c: u32) -> Color

Convert a packed u32 containing 0xRRGGBBAA into a Color

pub fn from_rgb_u32(c: u32) -> Color

Convert a packed u32 containing 0x00RRGGBB into a Color. This lets you do things like Color::from_rgb_u32(0xCD09AA) easily if you want.

pub fn to_rgba_u32(self) -> u32

Convert a Color into a packed u32, containing 0xRRGGBBAA as bytes.

pub fn to_rgb_u32(self) -> u32

Convert a Color into a packed u32, containing 0x00RRGGBB as bytes.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate 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 From<[f32; 4]> for Color

fn from(val: [f32; 4]) -> Self

Turns an [R, G, B, A] array of f32's into a Colorwith no format changes. All inputs should be in the range[0.0-1.0]`.

impl From<(f32, f32, f32)> for Color

fn from(val: (f32, f32, f32)) -> Self

Convert a (R, G, B) tuple of f32’s in the range [0.0-1.0] into a Color, with a value of 1.0 to for the alpha element (ie, no transparency.)

impl From<(f32, f32, f32, f32)> for Color

fn from(val: (f32, f32, f32, f32)) -> Self

Convert a (R, G, B, A) tuple of f32’s in the range [0.0-1.0] into a Color

impl From<(u8, u8, u8)> for Color

fn from(val: (u8, u8, u8)) -> Self

Convert a (R, G, B) tuple of u8’s in the range [0-255] into a Color, with a value of 255 for the alpha element (i.e., no transparency.)

impl From<(u8, u8, u8, u8)> for Color

fn from(val: (u8, u8, u8, u8)) -> Self

Convert a (R, G, B, A) tuple of u8’s in the range [0-255] into a Color

impl From<Color> for [f32; 4]

fn from(color: Color) -> Self

Convert a Color into an [R, G, B, A] array of f32’s in the range of [0.0-1.0].

impl From<Color> for (u8, u8, u8)

fn from(color: Color) -> Self

Convert a Color into a (R, G, B) tuple of u8’s in the range of [0-255], ignoring the alpha term.

impl From<Color> for (u8, u8, u8, u8)

fn from(color: Color) -> Self

Convert a Color into a (R, G, B, A) tuple of u8’s in the range of [0-255].

impl Into<String> for Color

fn into(self) -> String

Converts this type into the (usually inferred) input type.

impl PartialEq for Color

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