fn encode( encoding: &V::Encoding, canonical: &Canonical, like: Option<&V::Array>, ) -> VortexResult<Option<V::Array>>

Try to encode a canonical array into this encoding.

The given like array is passed as a template, for example if the caller knows that this encoding was successfully used previously for a similar array.

If the encoding does not support the given array (e.g. crate::arrays::ConstantEncoding was passed a non-constant array), then None is returned.
