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

Build a color from 4 0..255 components Unfortunately it may not be const fn due to https://github.com/rust-lang/rust/issues/57241 When const version is needed “color_u8” macro may be a workaround

pub fn to_vec(&self) -> Vec4

pub fn from_vec(vec: Vec4) -> Color

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<(), Error>

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl From<[f32; 4]> for Color

fn from(colors: [f32; 4]) -> Color

Converts to this type from the input type.

impl Into<[f32; 4]> for Color

fn into(self) -> [f32; 4]

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

impl Into<[u8; 4]> for Color

fn into(self) -> [u8; 4]

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.

impl Copy for Color

impl StructuralPartialEq for Color
