How To Install ghc-async on Fedora 36
Introduction
In this tutorial we learn how to install ghc-async on Fedora 36.
What is ghc-async
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’).
