name: async
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').
.
Changes in 2.0.1.3:
.
* Bump @base@ dependency to allow 4.6
.
Changes in 2.0.1.2:
.
* Bump @stm@ dependency to 2.4
.
Changes in 2.0.1.1:
.
* Safe Haskell support: @Control.Concurrent.Async@ is now @Trustworthy@
.
Changes in 2.0.1.0:
.
* Added a @Functor@ instance for @Async@
.
* Added @asyncBound@, @asyncOn@, @asyncWithUnmask@, @asyncOnWithUnmask@, @withAsyncBound@, @withAsyncOn@, @withAsyncWithUnmask@, @withAsyncOnWithUnmask@.
.
* Added @mapConcurrently@
.
* Added @Concurrently@ (with @Applicative@ and @Alternative@ instances)
