Struct wgpu_profiler::GpuProfilerQuery

pub struct GpuProfilerQuery {
    pub label: String,
    pub pid: u32,
    pub tid: ThreadId,
    /* private fields */
}

An inflight query for the profiler.

If timer queries are enabled, this represents a reserved timer query pair on one of the profiler’s query sets. Must be closed by calling [GpuProfiler::end_query].

Emitted by [GpuProfiler::begin_query]/[GpuProfiler::begin_pass_query] and consumed by [GpuProfiler::end_query].

label: String

The label assigned to this query. Will be moved into GpuProfilerQuery::label once the query is fully processed.

pid: u32

The process id of the process that opened this query.

tid: ThreadId

The thread id of the thread that opened this query.

Implementations

impl GpuProfilerQuery

pub fn render_pass_timestamp_writes( &self ) -> Option<RenderPassTimestampWrites<'_>>

Use the reserved query for render pass timestamp writes if any.

Use this only for a single render/compute pass, otherwise results will be overwritten. Only ever returns Some for queries that were created using [GpuProfiler::begin_pass_query].

pub fn compute_pass_timestamp_writes( &self ) -> Option<ComputePassTimestampWrites<'_>>

Use the reserved query for compute pass timestamp writes if any.

Use this only for a single render/compute pass, otherwise results will be overwritten. Only ever returns Some for queries that were created using [GpuProfiler::begin_pass_query].

pub fn with_parent(self, parent: Option<&GpuProfilerQuery>) -> Self

Makes this scope a child of the passed scope.
