# The devel/hs-async port

## hs-async-2.0.1.5 – asynchronous IO operations

## Description

    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').
