Struct SortedScanQuery 

pub struct SortedScanQuery<'a, K> { /* private fields */ }

Materialized, sorted view of findings selected by a ScanQuery.

This type owns only the vector of borrowed (source, finding) pairs. Source keys and findings remain owned by the originating ScanResults.

Implementations

impl<'a, K> SortedScanQuery<'a, K>

pub const fn len(&self) -> usize

Returns the number of sorted findings.

pub const fn count(&self) -> usize

Returns the number of sorted findings.

pub const fn has_matches(&self) -> bool

Returns true when the sorted query contains at least one finding.

pub const fn is_empty(&self) -> bool

Returns true when the sorted query contains no findings.

pub fn iter( &self, ) -> impl DoubleEndedIterator<Item = (&'a K, &'a Finding)> + ExactSizeIterator + '_

Iterates over sorted (source, finding) pairs.

pub fn first(&self) -> Option<(&'a K, &'a Finding)>

Returns the first sorted finding, if any.

pub fn last(&self) -> Option<(&'a K, &'a Finding)>

Returns the last sorted finding, if any.

pub fn as_slice(&self) -> &[(&'a K, &'a Finding)]

Returns the sorted findings as a borrowed slice.

pub fn to_vec(&self) -> Vec<(&'a K, &'a Finding)>

Returns the sorted borrowed pairs as a new vector.

Only references are copied; source keys and findings are not cloned.

pub fn into_vec(self) -> Vec<(&'a K, &'a Finding)>

Consumes the sorted query and returns its borrowed pairs without copying the vector.
