impl VTable for ListVTable

type Array = ListArray

type Encoding = ListEncoding

type ArrayVTable = ListVTable

type CanonicalVTable = ListVTable

type OperationsVTable = ListVTable

type ValidityVTable = ValidityVTableFromValidityHelper

type VisitorVTable = ListVTable

type ComputeVTable = NotSupported

Optionally enable implementing dynamic compute dispatch for this encoding. Can be disabled by assigning to the NotSupported type.
