name: async version: 2.2.4 -- don't forget to update ./changelog.md! 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'). license: BSD3 license-file: LICENSE author: Simon Marlow maintainer: Simon Marlow copyright: (c) Simon Marlow 2012 category: Concurrency build-type: Simple cabal-version: >=1.10 homepage: https://github.com/simonmar/async bug-reports: https://github.com/simonmar/async/issues tested-with: GHC == 9.2.0.20210821 GHC == 9.0.1 GHC == 8.10.4 GHC == 8.8.4 GHC == 8.6.5 GHC == 8.4.4 GHC == 8.2.2 GHC == 8.0.2 GHC == 7.10.3 GHC == 7.8.4 GHC == 7.6.3 GHC == 7.4.2 GHC == 7.2.2 GHC == 7.0.4 extra-source-files: changelog.md bench/race.hs source-repository head type: git location: https://github.com/simonmar/async.git library default-language: Haskell2010 other-extensions: CPP, MagicHash, RankNTypes, UnboxedTuples if impl(ghc>=7.1) other-extensions: Trustworthy exposed-modules: Control.Concurrent.Async build-depends: base >= 4.3 && < 4.17, hashable >= 1.1.2.0 && < 1.4, stm >= 2.2 && < 2.6 test-suite test-async default-language: Haskell2010 type: exitcode-stdio-1.0 hs-source-dirs: test main-is: test-async.hs build-depends: base >= 4.3 && < 4.17, async, stm, test-framework, test-framework-hunit, HUnit flag bench default: False executable concasync if !flag(bench) buildable: False default-language: Haskell2010 hs-source-dirs: bench main-is: concasync.hs build-depends: base, async, stm ghc-options: -O2 executable conccancel if !flag(bench) buildable: False default-language: Haskell2010 hs-source-dirs: bench main-is: conccancel.hs build-depends: base, async, stm ghc-options: -O2 -threaded executable race if !flag(bench) buildable: False default-language: Haskell2010 hs-source-dirs: bench main-is: race.hs build-depends: base, async, stm ghc-options: -O2 -threaded
