stm-orelse-io-0.1: Choose between the return value of an STM operation and an IO action.
Perform an IO action, and place its result in a TMVar. See
also Control.Concurrent.MVarIO for an MVar version.
run :: IO a -> IO (TMVar a)Source
run action returns a TMVar immediately. The result of
action will be placed in said TMVar. If the TMVar is full
when action completes, the return value is lost (i.e. we do not
wait for an empty TMVar).
