mapToJSON :: [(Text, PersistValue)] -> Textpersistent-mtl Database.Persist.Sql.Shim Convert map (list of tuples) into textual representation of JSON object. This is a type-constrained synonym for toJsonText.
mapToJSON :: [(Text, PersistValue)] -> Textpersistent-redis Database.Persist.Redis Convert map (list of tuples) into textual representation of JSON object. This is a type-constrained synonym for toJsonText.
mapM :: (Traversable t, Monad m) => (a -> m b) -> t a -> m (t b)pinch Pinch.Internal.FoldList Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.
Examples
mapM is literally a traverse with a type signature restricted to Monad. Its implementation may be more efficient due to additional power of Monad.mapRequestMessage :: (Message -> Message) -> Request o -> Request opinch Pinch.Server Map the message contained in the request.
