Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Describes the inversion of the assertion object

The inversion decorates the source assertion switching its message (from wrong to right) and reverting its ‘check`.

Examples:

Adult = Assertion.about :name, :age do
  age >= 18
end

assertion = Adult.new
inversion = Inversion.new(assertion)

assertion.call.valid? == inversion.call.invalid? # => true
