Struct vulkano::query::QueriesRange

pub struct QueriesRange<'a> { /* fields omitted */ }

A reference to a range of queries.

This is created through QueryPool::queries_range.

Implementations

impl<'a> QueriesRange<'a>

pub fn pool(&self) -> &'a QueryPool

Returns a reference to the query pool.

pub fn range(&self) -> Range<u32>

Returns the range of queries represented.

pub fn get_results<T>(
    &self,
    destination: &mut [T],
    flags: QueryResultFlags
) -> Result<bool, GetResultsError> where
    T: QueryResultElement, 

Copies the results of this range of queries to a buffer on the CPU.

self.pool().ty().result_size() elements will be written for each query in the range, plus 1 extra element per query if QueryResultFlags::with_availability is enabled. The provided buffer must be large enough to hold the data.

true is returned if every result was available and written to the buffer. false is returned if some results were not yet available; these will not be written to the buffer.
