pub enum QueryType {
Occlusion,
PipelineStatistics(PipelineStatisticsTypes),
Timestamp,
}
Expand description
Type of query contained in a QuerySet.
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 [Device::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.
