Jens Geyer commented on THRIFT-5314:
------------------------------------
> Is this intended?
Thrift APIs are allowing for soft-versioning, so aside from a few constraints
basically anything can change in an IDL file. Especially adding more enum
values is not really something unusual, so the Rust implementation should be
enaboed to handle such a case of it curretly does not work..
> Enum forward compatibility
> --------------------------
>
> Key: THRIFT-5314
> URL: https://issues.apache.org/jira/browse/THRIFT-5314
> Project: Thrift
> Issue Type: Bug
> Components: Rust - Compiler, Rust - Library
> Affects Versions: 0.13.0
> Reporter: Remi Dettai
> Priority: Major
>
> 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:
