defaultMonadLoggerLog :: (MonadIO m, HasLogger r, MonadReader r m, ToLogStr msg) => Loc -> LogSource -> LogLevel -> msg -> m () Source #

Default implementation for ML.MonadLogger

setLogLevel :: (MonadUnliftIO m, MonadLogger m) => LogStateHandle -> Maybe LogLevel -> m () Source #

Set the desired log-level for the logger

Will initialize the logger if it was not yet initialized. Otherwise will just override the wanted log level.

forceLogInitialization :: (MonadUnliftIO m, MonadLogger m) => LogStateHandle -> m () Source #

Initialize log to debug-level in case it is not yet initialized

Useful for handling application failures before the log-level is set. So that errors are reported instead of stay silent in the queue.
