I'm working on our GCP Spring Data integration for Spanner (https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-data-spanner), and noticed that Struct has getter methods for singular or array for all types other than Struct.

I know that STRUCTs can only be created in SQL queries and that STRUCTs are only allowed as ARRAYs of STRUCTs at the root level of the query. This lines up with only having the getStructList method, but
STRUCTs can have nested STRUCTs singularly ( like STRUCT<int64, STRUCT<boolean,string>> ). How can we access that inner STRUCT in java? Would it just be getting the first element of getStructList's result?

Thanks!
