> I am pretty new to the codebase, but I have seen that DictionaryArray is not implemented in the Rust implementation.
> I went through the list of issues and I could not see any work on this. Is there any blocker?
>  
> The specification is a bit [short|https://arrow.apache.org/docs/format/Layout.html#dictionary-encoding] or even [non-existant|https://arrow.apache.org/docs/format/Metadata.html#dictionary-encoding], so I am not sure how to implement it myself.
