class Monad m => MonadProgress m where Source #
Minimal complete definition
Methods
runProgressActions :: String -> [ProgressAction m ()] -> m () Source #
run a list of ProgressActions. In some monads (typically IO-based ones),
the progress and error messages will be used. In others they will be
ignored and just the actions will be run.
Instances
| MonadProgress DefaultIO Source # | |
| Monad m => MonadProgress (TreeMonad m) Source # | |
data ProgressAction m a Source #
a monadic action, annotated with a progress message that could be printed out while running the action, and a message that could be printed out on error. Actually printing out these messages is optional to allow non-IO monads to just run the action.
silentlyRunProgressActions :: Monad m => String -> [ProgressAction m ()] -> m () Source #
run a list of ProgressActions without any feedback messages
