[jira] [Created] (ARROW-11365) [Rust] [Parquet] Implement parsers for v2 of the text schema

Neville Dipale created ARROW-11365:
--------------------------------------

             Summary: [Rust] [Parquet] Implement parsers for v2 of the text schema
                 Key: ARROW-11365
                 URL: https://issues.apache.org/jira/browse/ARROW-11365
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Rust
    Affects Versions: 3.0.0
            Reporter: Neville Dipale


V2 of the writer produces schema like:

    required INT32 fieldname INTEGER(32, true);

We should support parsing this format, as it maps to logical types.
I'm unsure of what the implications are for fields that don't have a logical type representation, but have a converted type (e.g. INTERVAL). We can try write a V2 file with parquet-cpp and observe the behaviour.
