https://golang.org/ref/spec#Type_declarations You need to use another strategy like struct embedding which *may *or *may not* work depending to your use case A field declared with a type but no explicit field name is an *anonymous > field*, also called an *embedded* field or an embedding of the type in > the struct. An embedded type must be specified as a type name T or as a > pointer to a non-interface type name *T, and T itself may not be a > pointer type. The unqualified type name acts as the field name. type xadvanced struct { *x } func(x *xadvanced)increment(){ x.y ++ fmt.Println(x.y) } I'd advise you do read the spec at least once, it's short and concise .
