> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Rust
> Reporter: Neville Dipale
> Assignee: meng qingyou
> Priority: Major
> Labels: pull-request-available
> Time Spent: 5.5h
> Remaining Estimate: 0h

> The biggest hurdle to adding field metadata is HashMap and HashSet not
> implementing Hash, Ord and PartialOrd.
> I was thinking of implementing the metadata as a Vec<(String, String)> to
> overcome this limitation, and then serializing correctly to JSON.
