impl VTable for FSSTVTable

type Array = FSSTArray

type Encoding = FSSTEncoding

type ArrayVTable = FSSTVTable

type CanonicalVTable = FSSTVTable

type OperationsVTable = FSSTVTable

type ValidityVTable = ValidityVTableFromChild

type VisitorVTable = FSSTVTable

type ComputeVTable = NotSupported

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