The package provides ways to create Async computations, wait for +their results, and cancel them. + +Using Async is safer than using threads in two ways: + + - When waiting for a thread to return a result, if the thread dies with + an exception then the caller must either re-throw the exception (wait) + or handle it (waitCatch); the exception cannot be ignored. + + - The API makes it possible to build a tree of threads that are + automatically killed when their parent dies (see withAsync). + +WWW: https://github.com/simonmar/async |
