What is the "equals greater than" operator => in Ruby?

In a Ruby on Rails tutorial, I am asked to type:

class Post < ActiveRecord::Base
    validates :name,  :presence => true  
    validates :title, :presence => true, :length => { :minimum => 5 }
end

I understand what this does, but I would like to know what the => operator is. In PHP-land, it links a key and a value in an associative array. Is it the same thing here? Is it a Ruby operator or a Rails operator?
