Constructors

CoAxiomRule
Fields coaxrName :: FastString coaxrAsmpRoles :: [Role] coaxrRole :: Role coaxrProves :: [TypeEqn] -> Maybe TypeEqn coaxrProves returns `Nothing` when it doesn't like the supplied arguments. When this happens in a coercion that means that the coercion is ill-formed, and Core Lint checks for that.
