Expand description

This module contains the VTable definitions for a Vortex encoding.

Structs§

EmptyArrayData: Empty array metadata struct for encodings with no per-array metadata.
NotSupported: Placeholder type used to indicate when a particular vtable is not supported by the encoding.
ValidityVTableFromChild: An implementation of the ValidityVTable for arrays that delegate validity entirely to a child array.
ValidityVTableFromChildSliceHelper: An implementation of the ValidityVTable for arrays that hold an unsliced validity and a slice into it.

ArrayPlugin: Registry trait for ID-based deserialization of arrays.
ArrayVTable: Alias for migration — downstream code can start using ArrayVTable. The array VTable encapsulates logic for an Array type within Vortex.
OperationsVTable
