Enum web_sys::GpuCanvasAlphaMode

pub enum GpuCanvasAlphaMode {
    Opaque = 0,
    Premultiplied = 1,
    // some variants omitted
}

The GpuCanvasAlphaMode enum.

This API requires the following crate features to be activated: GpuCanvasAlphaMode

This API is unstable and requires --cfg=web_sys_unstable_apis to be activated, as described in the wasm-bindgen guide

Variants

Opaque = 0

Premultiplied = 1

Implementations

impl GpuCanvasAlphaMode

pub fn from_js_value(obj: &JsValue) -> Option<GpuCanvasAlphaMode>

Trait Implementations

impl Clone for GpuCanvasAlphaMode

fn clone(&self) -> GpuCanvasAlphaMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GpuCanvasAlphaMode

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

Formats the value using the given formatter.

impl From<GpuCanvasAlphaMode> for JsValue

fn from(obj: GpuCanvasAlphaMode) -> JsValue

Converts to this type from the input type.

impl FromWasmAbi for GpuCanvasAlphaMode

type Abi = <JsValue as FromWasmAbi>::Abi

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

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for GpuCanvasAlphaMode

type Abi = <JsValue as IntoWasmAbi>::Abi

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

fn into_abi(self) -> Self::Abi

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

impl OptionFromWasmAbi for GpuCanvasAlphaMode

fn is_none(abi: &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 GpuCanvasAlphaMode

fn none() -> Self::Abi

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

impl PartialEq for GpuCanvasAlphaMode

fn eq(&self, other: &GpuCanvasAlphaMode) -> 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.
