Struct BlendState 

pub struct BlendState {
    pub color: BlendComponent,
    pub alpha: BlendComponent,
}

The full blend state of a single color target.

Alpha blending is BlendComponent { operation: Add, source: SourceAlpha, destination: OneMinusSourceAlpha } on both the color and the alpha channel; replacing the source and keeping the destination is how a fade-to-black and other multiply blends are expressed.

Fields

color: BlendComponent

The blend applied to the RGB channels.

alpha: BlendComponent

The blend applied to the alpha channel, which is frequently not the same as the color blend.

Implementations

impl BlendState

Named constructors for the pipeline state structs.

pub fn alpha_over() -> Self

Alpha blending applied identically to the color and the alpha channel, which is what an ordinary translucent surface wants.

Returns

• Self - The assembled blend state.

pub fn get_color(&self) -> BlendComponent

pub fn get_alpha(&self) -> BlendComponent
