ratioPersister :: Integral a => Persister a -> Persister (Ratio a)Source

maybePersister :: Persister a -> Persister (Maybe a)Source

Persister for 'Maybe a' built from a specified a persister. Uses a single bit to represent Nothing.

shortcutPersister :: InjectionM i => i a b -> Persister b -> Persister a -> Persister bSource

Takes persisters for 2 types, and an injection from the smaller type a to the larger type b, and gives a persister for the larger type which uses the smaller type representation when possible, plus one bit to identify which representation is used.

(>.) :: Super a b => Persister b -> Persister a -> Persister bSource

Specialization of shortcutPersister with the super injection.

listPersister :: List a => Persister (Listed a) -> Persister aSource

Persister for lists built from a specified element persister.
