Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

An RGBA color with 8 bits per channel.

Fields

r: u8

Red channel (0–255).

g: u8

Green channel (0–255).

b: u8

Blue channel (0–255).

a: u8

Alpha channel (0 = fully transparent, 255 = fully opaque).

pub const TABLEAU_10: [Color; 10]

The complete Tableau-10 categorical palette, in canonical order.

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

Creates a new color from individual RGBA components.

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

Creates a fully opaque color from RGB components (alpha = 255).

pub fn with_alpha(self, a: u8) -> Color

Returns a copy of this color with the alpha channel set to a.

pub fn from_hex(hex: &str) -> Option<Color>

Parses a hex color string such as "#4E79A7" or "4E79A7".

Returns None if the string is not a valid 6-digit hex 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 Copy for Color

impl Debug for Color

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

Formats the value using the given formatter.

impl Eq for Color

impl Hash for Color

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
