abstractNewtype :: Info -> Maybe (DataInfo ()) Source #
This function abstracts away newtype declaration, it turns them into
data declarations.
infoToDataD :: DataInfo () -> Dec Source #
Convert the reified information of the datatype to a definition.
normalCon :: Con -> (Name, [StrictType], Maybe Type) Source #
This function provides the name and the arity of the given data constructor, and if it is a GADT also its type.
getBinaryFArg :: Type -> Maybe Type -> Type Source #
Auxiliary function to extract the first argument of a binary type
application (the second argument of this function). If the second
argument is Nothing or not of the right shape, the first argument
is returned as a default.
