Struct Color 

pub struct Color(pub f32, pub f32, pub f32, pub f32);

A color value consisting of four floating point values for the color channels red, green, blue and alpha.

Various drawing methods accept color instances to be used as multiplicators in the drawing process, e.g. Sprite::draw() allows multiplying the sprite- texture’s color channels by given color.

pub fn r(&self) -> f32

Returns value of the instance’s red channel.

pub fn g(&self) -> f32

Returns value of the instance’s green channel.

pub fn b(&self) -> f32

Returns value of the instance’s blue channel.

pub fn a(&self) -> f32

Returns value of the instance’s alpha channel.

pub fn set(&mut self, value: Color)

Sets the instance’s channels from another color object.

pub fn set_r(&mut self, value: f32) -> &mut Color

Sets a value for the instance’s red channel

pub fn set_g(&mut self, value: f32) -> &mut Color

Sets a value for the instance’s green channel.

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.

Returns the “default value” for a type.

impl<'a> From<&'a Color> for [f32; 4]

fn from(source: &'a Color) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Color> for (f32, f32, f32, f32)

fn from(source: &'a Color) -> Self

Converts to this type from the input type.

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

where f32: From<T>,

fn from(source: (T, T, T, T)) -> Self

Converts to this type from the input type.

impl From<Color> for [f32; 4]

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.
