Functions

cast_fixed_size_list_to_list 🔒

Cast fixed size list arrays to list arrays, maintaining the lengths of the inner lists.

cast_fixed_size_list_to_list_inner 🔒

cast_fixed_size_list_to_list_view 🔒

Same as cast_fixed_size_list_to_list but output list view array.

cast_list 🔒

Casting between list arrays of different offset size (e.g. List -> LargeList)

cast_list_to_fixed_size_list 🔒

Cast list to fixed size list array. If any inner list size does not match the size of the output fixed size list array, depending on cast_options we either output NULL for that element (safe) or raise an error.

cast_list_to_list_view 🔒

Casting list arrays to list view.

cast_list_values 🔒

Casting between list arrays of same offset size; we cast only the inner type.

cast_list_view 🔒

Casting between list view arrays of different offset size (e.g. ListView -> LargeListView)

cast_list_view_to_fixed_size_list 🔒

Same as cast_list_to_fixed_size_list but for list view arrays.

cast_list_view_to_list 🔒

Casting list view arrays to list.

cast_list_view_values 🔒

Casting between list view arrays of same offset size; we cast only the inner type.

cast_single_element_fixed_size_list_to_values 🔒

Cast fixed size list array to inner values type, essentially flattening the lists.

cast_values_to_list 🔒

Converts a non-list array to a list array where every element is a single element list. NULLs in the original array become [NULL] (i.e. output list array contains no nulls since it wraps all input nulls in a single element list).

cast_values_to_list_view 🔒

Same as cast_values_to_list but output list view array.

list_view_visible_values 🔒

Returns the values of list_view from the lowest offset to the highest end of its rows, and the offsets of the rows into those values. As rows can be in any order, these values can include some that no row uses.

list_visible_values 🔒

Returns the part of list.values() that the rows use, with the offsets adjusted to start at 0. For a sliced list, this drops the values outside the slice.
