Synopsis

Run IO operations asynchronously and wait for their results

Description

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).
