Enum BlendEquation

pub enum BlendEquation {
    FuncAdd = 32_774,
    FuncSubstract = 32_778,
    FuncReverseSubtract = 32_779,
    Min = 32_775,
    Max = 32_776,
}

Constants passed to WebGLRenderingContext.blendEquation() or WebGLRenderingContext.blendEquationSeparate() to control how the blending is calculated (for both, RBG and alpha, or separately).

Variants

FuncAdd = 32_774

Passed to blendEquation or blendEquationSeparate to set an addition blend function.

FuncSubstract = 32_778

Passed to blendEquation or blendEquationSeparate to specify a subtraction blend function (source - destination).

FuncReverseSubtract = 32_779

Passed to blendEquation or blendEquationSeparate to specify a reverse subtraction blend function (destination - source).

Min = 32_775

Minimum of source and destination,

Max = 32_776

Maximum of source and destination,

Trait Implementations

impl Clone for BlendEquation

fn clone(&self) -> BlendEquation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlendEquation

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

Formats the value using the given formatter.

impl From<BlendEquation> for JsValue

fn from(value: BlendEquation) -> Self

Converts to this type from the input type.

impl FromWasmAbi for BlendEquation

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 BlendEquation

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 BlendEquation

fn is_none(val: &Self::Abi) -> 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 BlendEquation

fn none() -> Self::Abi

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

impl TryFromJsValue for BlendEquation

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value( value: JsValue, ) -> Result<Self, <BlendEquation as TryFromJsValue>::Error>

Performs the conversion.

impl VectorFromWasmAbi for BlendEquation

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[BlendEquation]>

impl VectorIntoJsValue for BlendEquation

fn vector_into_jsvalue(vector: Box<[BlendEquation]>) -> JsValue

impl VectorIntoWasmAbi for BlendEquation

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[BlendEquation]>) -> Self::Abi

impl WasmDescribe for BlendEquation

fn describe()

impl WasmDescribeVector for BlendEquation

fn describe_vector()

impl Copy for BlendEquation
