Documentation
data Log :: Effect where Source #
The default high-level effect for simple text messages. To be used with the severity constructors:
import qualified Polysemy.Log as Log prog = do Log.debug "debugging…" Log.warn "warning!"
Interpreters should preprocess and relay the message to DataLog.
