System.Wlog.Concurrent

This module introduces functions that allow to run action in parallel with logging.

Documentation

data WaitingDelta

Data type to represent waiting strategy for printing warnings if action take too much time.

Constructors

WaitOnce (Time Second)

wait s seconds and stop execution

WaitLinear (Time Second)

wait s, s * 2, s * 3 , s * 4 , ... seconds

WaitGeometric (Time Second) RatioNat

wait m, m * q, m * q^2, m * q^3, ... microseconds

Methods

showsPrec :: Int -> WaitingDelta -> ShowS

show :: WaitingDelta -> String

showList :: [WaitingDelta] -> ShowS

type CanLogInParallel m = (MonadBaseControl IO m, WithLoggerIO m)

Constraint for something that can be logged in parallel with other action.

logWarningLongAction :: forall m a. CanLogInParallel m => (Text -> m ()) -> WaitingDelta -> Text -> m a -> m a

Run action and print warning if it takes more time than expected.

logWarningWaitOnce :: CanLogInParallel m => Time Second -> Text -> m a -> m a

Specialization of logWarningLongAction with WaitOnce.

logWarningWaitLinear :: CanLogInParallel m => Time Second -> Text -> m a -> m a

Specialization of logWarningLongAction with WaiLinear.

logWarningWaitInf :: CanLogInParallel m => Time Second -> Text -> m a -> m a

Specialization of logWarningLongAction with WaitGeometric with parameter 1.3. Accepts Second.
