>             Project: Thrift
>          Issue Type: Bug
>          Components: Rust - Compiler, Rust - Library

> It seems that enums in the Rust implem are not forward compatible. As Thrift enums are
mapped 1:1 to Rust enum, if a newer Thrift definition adds a case to an enum, an error will
be returned when parsing the message.
> Is this intended? Is there a workaround?
> (We met this problem in the Rust parquet implem: https://issues.apache.org/jira/browse/ARROW-10553)
