pub struct QueryPool { /* fields omitted */ }
A collection of one or more queries of a particular type.
Implementations
impl QueryPool
[src]
impl QueryPool
[src]pub fn new(
device: Arc<Device>,
ty: QueryType,
num_slots: u32
) -> Result<QueryPool, QueryPoolCreationError>
[src]
pub fn new(
device: Arc<Device>,
ty: QueryType,
num_slots: u32
) -> Result<QueryPool, QueryPoolCreationError>
[src]Builds a new query pool.
pub fn query(&self, index: u32) -> Option<Query<'_>>
[src]
pub fn query(&self, index: u32) -> Option<Query<'_>>
[src]Returns a reference to a single query slot, or None
if the index is out of range.
pub fn queries_range(&self, range: Range<u32>) -> Option<QueriesRange<'_>>
[src]
pub fn queries_range(&self, range: Range<u32>) -> Option<QueriesRange<'_>>
[src]Returns a reference to a range of queries, or None
if out of range.
Panic
Panics if the range is empty.
