Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Enables accessors and predicate methods for values in the options hash. This can be used to pass information to links when rendering breadcrumbs manually.

link = Link.new(:my_crumb, "My Crumb", my_path, title: "Test Title", other_value: "Other")
link.title?       # => true
link.title        # => "Test Title"
link.other_value? # => true
link.other_value  # => "Other"
link.some_other?  # => false
link.some_other   # => nil
