NativeValue

NativeValue serves as a wrapper type to allow us to implement Hash and Eq on all primitive types.

NullArray

A array where all values are null.

PrimitiveArray

A primitive array that stores native types in a contiguous buffer of memory, along with an optional validity child.

PrimitiveEncoding

StructArray

A struct array that stores multiple named fields as columns, similar to a database row.

StructEncoding

StructVTable

TemporalArray

An array wrapper for primitive values that have an associated temporal meaning.

VarBinArray

Functions

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.

is_compatible_decimal_value_type

True if value_type can represent every value of the type dtype.

list_from_list_view

Creates a ListArray from a ListViewArray.

list_view_from_list

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

narrowed_decimal

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

recursive_list_from_list_view

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

smallest_decimal_value_type

Maps a decimal precision into the smallest type that can represent it.
