class (MonadLogger m, MonadIO m) => MonadLoggerIO m where Source #

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.

Arguments

:: (MonadBaseControl IO m, MonadIO m)
