Constants passed to WebGLRenderingContext.blendFunc() or WebGLRenderingContext.blendFuncSeparate() to specify the blending mode (for both, RBG and alpha, or separately).

Variants

Zero

Passed to blendFunc or blendFuncSeparate to turn off a component.

One

Passed to blendFunc or blendFuncSeparate to turn on a component.

SrcColor

Passed to blendFunc or blendFuncSeparate to multiply a component by the source elements color.

OneMinusSrcColor

Passed to blendFunc or blendFuncSeparate to multiply a component by one minus the source elements color.

SrcAlpha

Passed to blendFunc or blendFuncSeparate to multiply a component by the source’s alpha.

OneMinusSrcAlpha

Passed to blendFunc or blendFuncSeparate to multiply a component by one minus the source’s alpha.

DstAlpha

Passed to blendFunc or blendFuncSeparate to multiply a component by the destination’s alpha.

OneMinusDstAlpha

Passed to blendFunc or blendFuncSeparate to multiply a component by one minus the destination’s alpha.

DstColor

Passed to blendFunc or blendFuncSeparate to multiply a component by the destination’s color.

OneMinusDstColor

Passed to blendFunc or blendFuncSeparate to multiply a component by one minus the destination’s color.

SrcAlphaSaturate

Passed to blendFunc or blendFuncSeparate to multiply a component by the minimum of source’s alpha or one minus the destination’s alpha.

ConstantColor

Passed to blendFunc or blendFuncSeparate to specify a constant color blend function.

OneMinusConstantColor

Passed to blendFunc or blendFuncSeparate to specify one minus a constant color blend function.

ConstantAlpha

Passed to blendFunc or blendFuncSeparate to specify a constant alpha blend function.

OneMinusConstantAlpha

Passed to blendFunc or blendFuncSeparate to specify one minus a constant alpha blend function.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl FromWasmAbi for BlendMode

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for BlendMode

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for BlendMode

fn is_none(val: &u32) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for BlendMode

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl WasmDescribe for BlendMode

fn describe()

impl Copy for BlendMode
