Struct Color

pub struct Color {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: u8,
}

A color with red, green, blue, and alpha components, in a byte each.

Fields

red: u8

The red component.

green: u8

The green component.

blue: u8

The blue component.

alpha: u8

The alpha component.

Implementations

impl Color

pub fn from_floats(red: f32, green: f32, blue: f32, alpha: f32) -> Self

Constructs a new Color value from float components. It expects the red, green, blue and alpha channels in that order, and all values will be clamped to the 0.0 … 1.0 range.

pub fn transparent() -> Self

Returns a transparent color.

pub fn new(red: u8, green: u8, blue: u8, alpha: u8) -> Self

Same thing, but with u8 values instead of floats in the 0 to 1 range.

pub fn red_f32(&self) -> f32

Returns the red channel in a floating point number form, from 0 to 1.

pub fn green_f32(&self) -> f32

Returns the green channel in a floating point number form, from 0 to 1.

pub fn blue_f32(&self) -> f32

Returns the blue channel in a floating point number form, from 0 to 1.

pub fn alpha_f32(&self) -> f32

Returns the alpha channel in a floating point number form, from 0 to 1.

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 Default for Color

fn default() -> Color

Returns the “default value” for a 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.
