|
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)
