classclass (MonadLogger m, MonadIO m) => MonadLoggerIO (m :: Type -> Type) where

#

An extension of MonadLogger for the common case where the logging action is a simple IO action. The advantage of using this typeclass is that the logging function itself can be extracted as a first-class value, which can make it easier to manipulate monad transformer stacks, as an example.

Methods

askLoggerIO :: m (Loc -> LogSource -> LogLevel -> LogStr -> IO ())
Request the logging function itself.
