Expand description

Alpha blend factor.

Alpha blending is very complicated: see the OpenGL or Vulkan spec for more information.

Corresponds to WebGPU GPUBlendFactor. Values using S1 requires Features::DUAL_SOURCE_BLENDING and can only be used with the first render target.

impl BlendFactor

source

pub fn ref_second_blend_source(&self) -> bool

Returns true if the blend factor references the second blend source.

Note that the usage of those blend factors require Features::DUAL_SOURCE_BLENDING.
