async: Run IO operations asynchronously and wait for their results
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
This package provides a higher-level interface over
threads, in which an Async a is a concurrent
thread that will eventually deliver a value of
type a. 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).
