[GitHub] [beam] jcking opened a new pull request #15154: Update Beam Go row coder to more completely handle schema interfaces

jcking opened a new pull request #15154:
URL: https://github.com/apache/beam/pull/15154


   Update Beam Go row coder to correctly handle schema interface providers for struct fields, map keys/values, and slice elements. Consider the following MyStruct and MyParDo and assume I have implemented a schema provider for `encoding/gob`.
   
   ```
   type MyStruct struct {
     // ...
   }
   
   func (ms *MyStruct) GobEncode() ([]byte, error) {
     // ...
   }
   
   func (ms *MyStruct) GobDecode(b []byte) error {
     // ...
   }
   
   type MyData struct {
     MyStruct MyStruct
   }
   ```
   
   If I encode and decode MyData using beam.NewElementEncoder and beam.NewElementDecoder, the result will be incorrect as Beam Go will fail to realize that MyStruct supports gob and ignore any unexported fields.
