Interfaces summary
In C# versions earlier than 8.0, an interface is like an abstract base class with only abstract members. A class or struct that implements the interface must implement all its members. Beginning with C# 8.0, an interface may define default implementations for some or all of its members.
What is the difference between struct and interface?
Structs and interfaces are Go's way of organizing methods and data handling. Where structs define the fields of an object, like a Person's first and last name. The interfaces define the methods; e.g. formatting and returning a Person's full name.
Can a struct have an interface?
Implementing an interface on a struct has no negative consequences whatsoever. Any variable of the interface type used to hold a struct will result in a boxed value of that struct being used.
