Module builtins 

Built-in compression schemes that use only vortex-array encodings.

These schemes produce arrays using types already in vortex-array (ConstantArray, DictArray, MaskedArray, etc.) and have no external encoding crate dependencies.

Structs

BinaryConstantScheme

Constant encoding for binary arrays with a single distinct value.

BinaryDictScheme

Dictionary encoding for low-cardinality binary values.

BoolConstantScheme

Constant encoding for bool arrays where all valid values are the same.

FloatConstantScheme

Constant encoding for float arrays with a single distinct value.

FloatDictScheme

Dictionary encoding for low-cardinality float values.

IntConstantScheme

Constant encoding for integer arrays with a single distinct value.

IntDictScheme

Dictionary encoding for low-cardinality integer values.

StringConstantScheme

Constant encoding for string arrays with a single distinct value.

StringDictScheme

Dictionary encoding for low-cardinality string values.

Functions
