Overview

Interfaces are not types.

Can only structs be interfaces, or there are other things that can be interfaces?

Declaration

The interface declaration is introduced by the type keyword, to indicated that this is a user-defined type, followed by the interface name and the keyword interface. Unlike in the struct's case, we don't define fields but a method set.

type MyInterface interface {
     functionName1() return_type
     functionName2() return_type
     ...
}
