boolean_to_utf8view

cast

Cast array to the provided data type and return a new Array with type to_type, if possible.

cast_default

cast_unchecked

date32_to_date64

Conversion of dates

date64_to_date32

Conversion of dates

primitive_as_primitive

Cast PrimitiveArray as a PrimitiveArray Same as number as to_number_type in rust

primitive_map_is_valid^⚠

Safety

primitive_to_boolean

Returns a BooleanArray where every element is different from zero. Validity is preserved.
