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

["Martin Tzvetanov Grigorov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-3331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17484337#comment-17484337 ] 

Martin Tzvetanov Grigorov commented on AVRO-3331:
-------------------------------------------------

Actually, you can get the Vec<u8> even now with:
{code:java}
let bytes = <Vec<u8>>::try_from(decimal);{code}
I will think about a better API!

> 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.
