Struct Color 

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

RGBA color value

Each component is stored as a u8 (0-255).

Fields

r: u8

Red component (0-255)

g: u8

Green component (0-255)

b: u8

Blue component (0-255)

a: u8

Alpha component (0-255, 255 = fully opaque)

Implementations

impl Color

pub const BLACK: Color

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

Create an RGB color (fully opaque)

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

Create an RGBA color

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

Create a color from a hex string (e.g., “#FF0000” or “#FF0000FF”)

pub fn to_hex(&self) -> String

Convert to hex string (e.g., “#FF0000”)

pub fn r_f32(&self) -> f32

Get the red component as a float (0.0-1.0)

pub fn g_f32(&self) -> f32

Get the green component as a float (0.0-1.0)

pub fn b_f32(&self) -> f32

Get the blue component as a float (0.0-1.0)

pub fn a_f32(&self) -> f32

Get the alpha component as a float (0.0-1.0)

pub const fn is_opaque(&self) -> bool

Check if the color is fully opaque

pub const fn is_transparent(&self) -> bool

Check if the color is fully transparent

pub fn from_name(name: &str) -> Option<Color>

Parse a color from a CSS/SVG color name (case-insensitive)

Supports all 140+ CSS3/SVG color keywords.

Examples

assert_eq!(Color::from_name("red"), Some(Color::rgb(255, 0, 0)));
assert_eq!(Color::from_name("Blue"), Some(Color::rgb(0, 0, 255)));
assert_eq!(Color::from_name("LIME"), Some(Color::rgb(0, 255, 0)));
assert_eq!(Color::from_name("aliceblue"), Some(Color::rgb(240, 248, 255)));

pub fn parse(input: &str) -> Option<Color>

Parse a color from a string (hex, or CSS/SVG color name)

Examples

assert_eq!(Color::parse("#FF0000"), Some(Color::rgb(255, 0, 0)));
assert_eq!(Color::parse("red"), Some(Color::rgb(255, 0, 0)));
assert_eq!(Color::parse("Blue"), Some(Color::rgb(0, 0, 255)));

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 Display for Color

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

Formats the value using the given formatter.

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.
