Martin Tzvetanov Grigorov commented on AVRO-3331:
-------------------------------------------------
You need to pass a reference to try_from:
{code:java}
<Vec<u8>>::try_from(&d); {code}

> Rust: Cannot extract Decimal value
> ----------------------------------

> 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.
