Enum HintTarget

pub enum HintTarget {
    GenerateMipmapHint = 33_170,
    FragmentShaderDerivativeHint = 35_723,
}

Constants passed to WebGLRenderingContext.hint() target argument

Variants

GenerateMipmapHint = 33_170

Hint for the quality of filtering when generating mipmap images with WebGLRenderingContext.generateMipmap().

FragmentShaderDerivativeHint = 35_723

Accuracy of the derivative calculation for the GLSL built-in functions: dFdx, dFdy, and fwidth.

Trait Implementations

impl Clone for HintTarget

fn clone(&self) -> HintTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HintTarget

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

Formats the value using the given formatter.

impl From<HintTarget> for JsValue

fn from(value: HintTarget) -> Self

Converts to this type from the input type.

impl FromWasmAbi for HintTarget

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 HintTarget

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 HintTarget

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 HintTarget

fn none() -> Self::Abi

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

impl TryFromJsValue for HintTarget

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for HintTarget

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

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

impl VectorIntoJsValue for HintTarget

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

impl VectorIntoWasmAbi for HintTarget

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

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

impl WasmDescribe for HintTarget

fn describe()

impl WasmDescribeVector for HintTarget

fn describe_vector()

impl Copy for HintTarget
