----------------------------------

             Summary: [Rust] support to convert bytes to fixed in resolve_fixed
                 Key: AVRO-3892
                 URL: https://issues.apache.org/jira/browse/AVRO-3892
             Project: Apache Avro
          Issue Type: Improvement
          Components: rust
            Reporter: zejiong dong


I'm working on iceberg-rs and converting value of iceberg between value of Avro using

```

let avro_value = to_value(iceberg_value).unwrap().resolve(&avro_schema).unwrap();

```

But I can't convert any byte-like type(binary or fixed) in iceberg to fixed type in avro. Any byte-like byte will convert to avro byte using serialize_bytes first and use convert to dedicated type use resolve. But [resolved_fixed|[https://github.com/apache/avro/blob/2b1955947ab446ad437f152ec2f3310ea399a015/lang/rust/avro/src/types.rs#L910]|https://github.com/apache/avro/blob/2b1955947ab446ad437f152ec2f3310ea399a015/lang/rust/avro/src/types.rs#L910],] can't convert bytes to fixed. So can we consider supporting converting bytes to fixed in resolve_fixed? I'm glad to send a PR if it sounds ok.
