Enum QueryTarget

pub enum QueryTarget {
    AnySamplesPassed = 35_887,
    AnySamplesPassedConservative = 36_202,
    TransformFeedbackPrimitivesWritten = 35_976,
}

Constants passed to beginQuery

Variants

AnySamplesPassed = 35_887

Specifies an occlusion query: these queries detect whether an object is visible (whether the scoped drawing commands pass the depth test and if so, how many samples pass).

AnySamplesPassedConservative = 36_202

Same as above above, but less accurate and faster version.

TransformFeedbackPrimitivesWritten = 35_976

Number of primitives that are written to transform feedback buffers.

Trait Implementations

impl Clone for QueryTarget

fn clone(&self) -> QueryTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryTarget

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

Formats the value using the given formatter.

impl From<QueryTarget> for JsValue

fn from(value: QueryTarget) -> Self

Converts to this type from the input type.

impl FromWasmAbi for QueryTarget

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 QueryTarget

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 QueryTarget

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 QueryTarget

fn none() -> Self::Abi

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

impl TryFromJsValue for QueryTarget

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for QueryTarget

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

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

impl VectorIntoJsValue for QueryTarget

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

impl VectorIntoWasmAbi for QueryTarget

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

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

impl WasmDescribe for QueryTarget

fn describe()

impl WasmDescribeVector for QueryTarget

fn describe_vector()

impl Copy for QueryTarget
