[jira] [Created] (ARROW-10259) [Rust] Support field metadata

Neville Dipale created ARROW-10259:
--------------------------------------

             Summary: [Rust] Support field metadata
                 Key: ARROW-10259
                 URL: https://issues.apache.org/jira/browse/ARROW-10259
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Rust
            Reporter: Neville Dipale


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.
