[jira] [Created] (AVRO-3331) Rust: Cannot extract Decimal value

Thomas Schilling created AVRO-3331:
--------------------------------------

             Summary: Rust: Cannot extract Decimal value
                 Key: AVRO-3331
                 URL: https://issues.apache.org/jira/browse/AVRO-3331
             Project: Apache Avro
          Issue Type: Bug
          Components: rust
            Reporter: Thomas Schilling


The [Decimal|https://docs.rs/avro-rs/latest/avro_rs/struct.Decimal.html] type (as of 0.13) doesn't have any methods or trait implementations that allow users to extract the value. The only workaround I could think of would be to parse the output of the `Debug` implementation. But that's clearly very inefficient and fragile.

The (unreleased?) version 0.14 also seems to have the same issue ([source|https://github.com/apache/avro/blob/master/lang/rust/src/decimal.rs]).

It might just be enough to make the {{to_vec }}method public and specify how to interpret the result vector.
