typesafe-ruby

Description:

Adds typesafe macro to class Module, to provide type safe method declarations.

Usage

require 'typesafe'

Now you can use the typesafe macro in classes and modules.

Example:

class Foo
  typesafe(Integer)
  def bar a
    p a
  end
end

The method bar now only accepts arguments of type Integer. If an object of a different type is passed to foo it will raise an ArgumentError.

You can also use typed collections and varargs.

Example:

class Foo
  typesafe(Array[Integer])
  def bar a
    p a
  end

  typesafe(VarArgs[Integer])
  def baz *a
    p a
  end

  typesafe(Hash[String, Integer])
  def foobar a
    p a
  end
end
