Lift TypeExp

Methods

lift :: TypeExp -> Q Exp

fromType :: Type -> Q TypeExp

Get the type expression for a Type. Attempts to reduce the resulting type expression.

fromName :: Name -> Q TypeExp

Get the type expression for a Name. Attempts to reduce the resulting type expression.

substitute :: Name -> TypeExp -> TypeExp -> TypeExp

substitute name typ exp replaces all occurences of name in exp with typ.

substituteAll :: Map Name TypeExp -> TypeExp -> TypeExp

Just like substitute but for more variables.

reduce :: TypeExp -> TypeExp

Try to reduce the given type expression as much as possible.

match :: TypeExp -> TypeExp -> Maybe (Map Name TypeExp)

match pattern input pattern matches input against the given pattern.
