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.

Implementations

impl BlendFactor

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.

Trait Implementations

impl Clone for BlendFactor

fn clone(&self) -> BlendFactor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendFactor

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

Formats the value using the given formatter.

impl Hash for BlendFactor

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BlendFactor

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

This method tests for self and other values to be equal, and is used by ==.

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.
