The type of query that a query pool should perform.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Occlusion = 0

Tracks the number of samples that pass per-fragment tests (e.g. the depth test).

Used with the begin_query and end_query commands.

PipelineStatistics = 1

Tracks statistics on pipeline invocations and their input data.

Used with the begin_query and end_query commands.

Timestamp = 2

Writes timestamps at chosen points in a command buffer.

Used with the write_timestamp command.

AccelerationStructureCompactedSize = 1_000_150_000

Queries the size of data resulting from a CopyAccelerationStructureMode::Compact operation.

Used with the write_acceleration_structures_properties command.

AccelerationStructureSerializationSize = 1_000_150_001

Queries the size of data resulting from a CopyAccelerationStructureMode::Serialize operation.

Used with the write_acceleration_structures_properties command.

AccelerationStructureSerializationBottomLevelPointers = 1_000_386_000

For a top-level acceleration structure, queries the number of bottom-level acceleration structure handles that will be written during a CopyAccelerationStructureMode::Serialize operation.

Used with the write_acceleration_structures_properties command.

AccelerationStructureSize = 1_000_386_001

Queries the total size of an acceleration structure.

Used with the write_acceleration_structures_properties command.

MeshPrimitivesGenerated = 1_000_328_000

Queries the number of primitives emitted from a mesh shader that reach the fragment shader.

Used with the begin_query and end_query commands.

Trait Implementations

impl Clone for QueryType

fn clone(&self) -> QueryType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryType

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

Formats the value using the given formatter.

impl From<QueryType> for QueryType

fn from(val: QueryType) -> Self

Converts to this type from the input type.

impl Hash for QueryType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QueryType

fn eq(&self, other: &QueryType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<QueryType> for QueryType

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: QueryType) -> Result<Self, Self::Error>

Performs the conversion.
