Defines filter kernels
Structs§
- A builder to construct
FilterPredicate FilterBytesis created from a source [GenericByteArray] and can be used to build a new [GenericByteArray] by copying values from the source- A filtering predicate that can be applied to an [
Array] - An iterator of
usizewhose index in [BooleanArray] is true - An iterator of
(usize, usize)each representing an interval[start, end)whose slots of a bitmap [Buffer] are true.
Enums§
- The iteration strategy used to evaluate
FilterPredicate
Constants§
- If the filter selects more than this fraction of rows, use
SlicesIteratorto copy ranges of values. Otherwise iterate over individual rows usingIndexIterator
