Dyn-compatible VTable trait for a Vortex array encoding.

This trait provides extension points for arrays to implement various features of Vortex. It is split into multiple sub-traits to make it easier for consumers to break up the implementation, as well as to allow for optional implementation of certain features, for example compute functions.

It is recommended that you use crate::impl_encoding to assist in writing a new array encoding.

Required Methods

fn id(&self) -> EncodingId

Return the ID for this encoding implementation.

fn as_any(&self) -> &dyn Any

Return a reference to this encoding as a dyn Any for type erasure.

Trait Implementations

impl Hash for dyn EncodingVTable + '_

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl PartialEq for dyn EncodingVTable + '_

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
