Module vortex_array::compute

Compute kernels on top of Vortex Arrays.

We aim to provide a basic set of compute kernels that can be used to efficiently index, slice, and filter Vortex Arrays in their encoded forms.

Every array variant has the ability to implement their own efficient implementations of these operators, else we will decode, and perform the equivalent operator from Arrow.

Structs

• FilterMask
  Represents the mask argument to a filter function. Internally this will cache the canonical representation of the mask if it is ever used.
• LikeOptions
  Options for SQL LIKE function

Enums

• BinaryOperator
• FilterIter
• Operator
• SearchResult
  Result of performing search_sorted on an Array
• SearchSortedSide

Traits

• BinaryBooleanFn
• BinaryNumericFn
• CastFn
• CompareFn
• ComputeVTable
  VTable for dispatching compute functions to Vortex encodings.
• FillForwardFn
  Trait for filling forward on an array, i.e., replacing nulls with the last non-null value.
• FillNullFn
  Implementation of fill_null for an encoding.
• FilterFn
• IndexOrd
• InvertFn
• Len
• LikeFn
• ScalarAtFn
  Implementation of scalar_at for an encoding.
• SearchSorted
• SearchSortedFn
  Searches for value assuming the array is sorted.
• SearchSortedUsizeFn
• SliceFn
  Limit array to start…stop range
• TakeFn
