Overview

rdoc This module contains all the builtin contracts. If you want to use them, first:

import Contracts

And then use these or write your own!

A simple example:

Contract Num, Num => Num
def add(a, b)
  a + b
end

The contract is Contract Num, Num, Num. That says that the add function takes two numbers and returns a number.
