data OnBlocked

The runtime tries to run synchronous threads to completion. Sometimes it's not possible to continue running a thread, for example when the thread tries to take an empty MVar. The runtime can then either throw a WouldBlockException, aborting the blocking action, or continue the thread asynchronously.

Constructors

ContinueAsync

continue the thread asynchronously if blocked

ThrowWouldBlock

throw WouldBlockException if blocked
