Declaration of the RouteT monad transformer


RouteT Monad Transformer

newtype RouteT url m a Source

monad transformer for generating URLs

MonadReader r m => MonadReader r (RouteT url m) 
MonadState s m => MonadState s (RouteT url m) 
MonadWriter w m => MonadWriter w (RouteT url m) 
MonadTrans (RouteT url)

Associated Types

type URL m Source


askRouteFn :: m (URL m -> [(Text, Maybe Text)] -> Text) Source


Monad m => MonadRoute (RouteT url m) 

runRouteT :: (url -> RouteT url m a) -> (url -> [(Text, Maybe Text)] -> Text) -> url -> m a Source

convert a RouteT based route handler to a handler that can be used with the Site type

NOTE: this function used to be the same as unRouteT. If you want the old behavior, just call unRouteT.

mapRouteT :: (m a -> n b) -> RouteT url m a -> RouteT url n b Source

Transform the computation inside a RouteT.

withRouteT :: ((url' -> [(Text, Maybe Text)] -> Text) -> url -> [(Text, Maybe Text)] -> Text) -> RouteT url m a -> RouteT url' m a Source

Execute a computation in a modified environment

liftRouteT :: m a -> RouteT url m a Source

askRouteT :: Monad m => RouteT url m (url -> [(Text, Maybe Text)] -> Text) Source

nestURL :: (url1 -> url2) -> RouteT url1 m a -> RouteT url2 m a Source
