class Stannum::Constraints::Parameters::ExtraKeywords
Validates that the keywords passed to a method have no extra keys.
@example
keys = %[fuel mass size] constraint = Stannum::Constraints::Parameters::ExpectedKeywords.new(keys) constraint.matches?({}) #=> true constraint.matches?({ fuel: 'Monopropellant' }) #=> true constraint.matches?({ electric: true, fuel: 'Xenon' }) #=> false constraint.matches?({ fuel: 'LF/O', mass: '1 ton', size: 'Medium' }) #=> true constraint.matches?( { fuel: 'LF', mass: '2 tons', nuclear: true, size: 'Medium' } ) #=> false
