Description

The union data type has no getter function and as such, the only way to get to the data in the union is to create a struct

typedef struct avro_union_datum_t {
	struct avro_obj_t obj;
	int64_t discriminant;
	avro_datum_t value;
} avro_union_datum_t;

in your own include or code as the struct for this is in datum.h which is not installed with the library. In addition, there is a type warning when trying to use avro_record_get using the avro_union_datum_t.

Ideally there would be a getter that exposes the datum in the union.
