Trait DictEncoder 

pub trait DictEncoder: Send {
    // Required methods
    fn encode(
        &mut self,
        array: &ArrayRef,
        ctx: &mut ExecutionCtx,
    ) -> VortexResult<PrimitiveArray>;
    fn reset(&mut self) -> ArrayRef;
    fn codes_ptype(&self) -> PType;
}

Required Methods

fn encode( &mut self, array: &ArrayRef, ctx: &mut ExecutionCtx, ) -> VortexResult<PrimitiveArray>

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
