             Summary: Generate a method for retrieving IDL exceptions in Go 
without using reflection
                 Key: THRIFT-5792
                 URL: https://issues.apache.org/jira/browse/THRIFT-5792
             Project: Thrift
          Issue Type: Improvement
          Components: Go - Compiler
            Reporter: Long Bui


Currently, the only way to retrieve IDL exceptions in Go is by using 
[ExtractExceptionFromResult|https://github.com/apache/thrift/blob/1405831722ac0e1e1ba100801bf21073a0d17940/lib/go/thrift/exception.go#L141],
 and as you can see, this method uses reflection to traverse through all 
fields. This is not an effective approach when the Result structure is large.

Therefore, I propose adding an Exception() error method to the generated Result 
structure for retrieving IDL exceptions in an efficient way.
