Struct Rgba 

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

32-bit straight (non-premultiplied) RGBA color.

Matches SVG’s rgb() + opacity model and PDF’s RGB + CA/ca graphic-state model. Premultiplication is a rasterizer concern; this IR carries straight alpha to avoid lossy round-trips.

Fields

r: u8

g: u8

b: u8

a: u8

Implementations

impl Rgba

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

pub const fn opaque(r: u8, g: u8, b: u8) -> Self

Fully-opaque color with the given RGB triple.

Trait Implementations

impl Clone for Rgba

fn clone(&self) -> Rgba

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Rgba

impl Debug for Rgba

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

Formats the value using the given formatter.

impl Default for Rgba

fn default() -> Rgba

Returns the “default value” for a type.

impl Eq for Rgba

impl From<(u8, u8, u8)> for Rgba

fn from((r, g, b): (u8, u8, u8)) -> Self

Fully-opaque color with the given RGB triple.

impl From<(u8, u8, u8, u8)> for Rgba

fn from((r, g, b, a): (u8, u8, u8, u8)) -> Self

Converts to this type from the input type.

impl From<Rgba> for Paint

fn from(color: Rgba) -> Self

Wrap an Rgba in a Paint::Solid.

impl From<[u8; 4]> for Rgba

fn from([r, g, b, a]: [u8; 4]) -> Self

Converts to this type from the input type.

impl PartialEq for Rgba

fn eq(&self, other: &Rgba) -> 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.
