Struct webrender_api::ColorF

source ·
#[repr(C)]
pub struct ColorF { pub r: f32, pub g: f32, pub b: f32, pub a: f32, }
Expand description

Represents RGBA screen colors with floating point numbers.

All components must be between 0.0 and 1.0. An alpha value of 1.0 is opaque while 0.0 is fully transparent.

impl MallocSizeOf for ColorF

source§

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

source§

impl PartialEq for ColorF

source§

fn eq(&self, other: &ColorF) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
