Functions

chunk_range

Computes the index range for a chunk, accounting for slice offset.

compute_is_constant

Assumes any floating point has been cast into its bit representation for which != and !is_eq are the same Assumes there’s at least 1 value in the slice, which is an invariant of the entry level function.

format_indices

list_from_list_view

Creates a ListArray from a ListViewArray. The resulting ListArray will not have any leading or trailing garbage data.

list_view_from_list

Creates a ListViewArray from a ListArray by computing sizes from offsets.

mask_validity_canonical

TODO: replace usage of compute fn. Apply a validity mask to a canonical array, ANDing with existing validity.

narrowed_decimal

Attempt to narrow the decimal array to any smaller supported type.

patch_chunk

Patches a chunk of decoded values.

recursive_list_from_list_view

Recursively converts all ListViewArrays to ListArrays in a nested array structure.

take_canonical

Take from a canonical array using indices (codes), returning a new canonical array.

varbin_scalar

Unions

BinaryView

A view over a variable-length binary value.
