In Ruby, what is the equivalent to an interface in C#?

Question

I\'m currently trying to learn Ruby and I\'m trying to understand more about what it offers in terms of encapsulation and contracts.

In C# a contract can be defined

Answer 1

Ruby doesn't really have them; interfaces and contracts generally live more in the static world, rather than the dynamic.

There is a gem called Handshake that can implement informal contracts, if you really need it.
