Required Methods

fn encode(&mut self, array: &dyn Array) -> ArrayRef

Assign dictionary codes to the given input array.

fn reset(&mut self) -> ArrayRef

Clear the encoder state to make it ready for a new round of decoding.

fn codes_ptype(&self) -> PType

Returns the PType of the codes this encoder produces.
