Implementations§

Source §

impl RowEncodedKeys

Source

pub fn gen_partition_idxs<const BUILD_SKETCHES: bool>( &self, partitioner: &HashPartitioner, partition_idxs: &mut [Vec<IdxSize>], sketches: &mut [CardinalitySketch], partition_nulls: bool, )

Source

pub fn gen_partitioned_gather_idxs( &self, partitioner: &HashPartitioner, gathers_per_key: &[IdxSize], gather_idxs: &mut Vec<ChunkId<32>>, )

Source

pub unsafe fn gather(&self, idxs: &[IdxSize]) -> Self

§Safety

The indices must be in-bounds.
