Struct Color 

#[repr(C)]
pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

An RGBA color with FFI-safe memory layout.

Components are stored as f32 values, typically in the range [0.0, 1.0]. Values outside this range are allowed for HDR rendering.

Fields

r: f32

The red component of the color.

g: f32

The green component of the color.

b: f32

The blue component of the color.

a: f32

The alpha (transparency) component of the 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<'de> Deserialize<'de> for Color

fn deserialize<__D>( __deserializer: __D, ) -> Result<Color, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FfiColor> for Color

fn from(c: FfiColor) -> Color

Converts to this type from the 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 Serialize for Color

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Tweenable for Color

fn lerp(self, other: Color, t: f32) -> Color

Linearly interpolates between self and other.

fn tween(self, other: Self, t: f32, easing: fn(f32) -> f32) -> Self

Interpolates between self and other using an easing function.

impl Copy for Color

impl StructuralPartialEq for Color
