Thanks @zeroshade
I think the rust `flight.proto` is too old.
In the rust side, the definition is
```
/*
* Wrap the result of a getSchema call
*/
message SchemaResult {
// schema of the dataset as described in Schema.fbs::Schema.
bytes schema = 1;
}
```
@alamb Maybe we should update the `.proto` in the rust side.
