:: DeveloperApi :: A StructType object can be constructed by
StructType(fields: Seq[StructField])For a StructType object, one or multiple StructFields can be extracted by names. If multiple StructFields are extracted, a StructType object will be returned. If a provided name does not have a matching field, it will be ignored. For the case of extracting a single StructField, a
nullwill be returned. Example:A org.apache.spark.sql.Row object is used as a value of the StructType. Example:
