local :: forall a r b. Member (DataLog a) r => (a -> a) -> Sem r b -> Sem r b

Stores the provided function in the interpreter and applies it to all log messages emitted within the higher-order thunk that's the second argument.

dataLog :: forall a r. Member (DataLog a) r => a -> Sem r ()

Schedule an arbitrary value for logging.

type Logger = DataLog (LogEntry LogMessage)

Alias for the logger with the default message type used by Log.
