GHC.Event.TimeOut
Description
Common Timer definitions shared between WinIO and RIO.
Synopsis
- type TimeoutQueue = PSQ TimeoutCallback
- type TimeoutCallback = IO ()
- type TimeoutEdit = TimeoutQueue -> TimeoutQueue
- newtype TimeoutKey = TK Unique
Documentation
type TimeoutQueue = PSQ TimeoutCallback Source #
A priority search queue, with timeouts as priorities.
type TimeoutCallback = IO () Source #
Warning: since the TimeoutCallback is called from the I/O manager, it must
not throw an exception or block for a long period of time. In particular,
be wary of throwTo and killThread:
if the target thread is making a foreign call, these functions will block
until the call completes.
type TimeoutEdit = TimeoutQueue -> TimeoutQueue Source #
An edit to apply to a TimeoutQueue.
newtype TimeoutKey Source #
A timeout registration cookie.
