Enum vulkano::query::QueryType

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

The type of query that a query pool should perform.

Variants

Occlusion

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

PipelineStatistics(QueryPipelineStatisticFlags)

Tracks statistics on pipeline invocations and their input data.

Timestamp

Writes timestamps at chosen points in a command buffer.

Implementations

impl QueryType

pub const fn result_len(&self) -> DeviceSize

Returns the number of QueryResultElements that are needed to hold the result of a single query of this type.

• For Occlusion and Timestamp queries, this returns 1.
• For PipelineStatistics queries, this returns the number of statistics flags enabled.

If the results are retrieved with QueryResultFlags::with_availability enabled, then an additional element is required per query.
