Enum wgpu::QueryType

pub enum QueryType {
    Occlusion,
    PipelineStatistics(PipelineStatisticsTypes),
    Timestamp,
}

Type of query contained in a QuerySet.

Corresponds to WebGPU GPUQueryType.

Variants

Occlusion

Query returns a single 64-bit number, serving as an occlusion boolean.

PipelineStatistics(PipelineStatisticsTypes)

Query returns up to 5 64-bit numbers based on the given flags.

See PipelineStatisticsTypes’s documentation for more information on how they get resolved.

Features::PIPELINE_STATISTICS_QUERY must be enabled to use this query type.

Timestamp

Query returns a 64-bit number indicating the GPU-timestamp where all previous commands have finished executing.

Must be multiplied by Queue::get_timestamp_period to get the value in nanoseconds. Absolute values have no meaning, but timestamps can be subtracted to get the time it takes for a string of operations to complete.

Features::TIMESTAMP_QUERY must be enabled to use this query type.
