Async extensions for Nils Luck's Optional library.
It allows you to chain Task<Option<T>> and Task<Option<T, TException>> without having to use
Optional library will include its own async extensions. However, at this point they don't provide as much flexibility. To avoid conflicts, the namespace of this library has been changed to
Optional.Asyncwas not meant to be published as a standalone library. It's a collection of extension methods that I had to implement on my own while working with
Optional. There are currently no tests and I don't plan on extensively maintaining it. Still, most of the extensions you'll find here are currently being used/have been used for the past year in production code without issues.
Say you have the following asynchronous functions and you want to execute them in order:
Task<Option<User, Error>> CheckIfUserIsAuthorized(string userId, string category); Task<Option<CloudRecord, Error>> StoreTheFileIntoTheCloud(File file, string category); Task<Option<Guid, Error>> StoreDatabaseLog(CloudRecord record); Task<Option<DocumentProcessedResult, Error>> SendToExternalService(Guid key);
Currently, there is no built-in mechanism inside
Optional that allows you to chain these calls. What
Optional.Async provides is the ability to compose asynchronous functions. The following would be valid syntax:
Task<Option<DocumentProcessedResult, Error>> ProcessDocument( string userId, string category, File file) => CheckIfUserIsAuthorized(userId, category).FlatMapAsync(user => StoreTheFileIntoTheCloud(file, category).FlatMapAsync(cloudRecord => StoreDatabaseLog(cloudRecord).FlatMapAsync(uniqueKey => SendToExternalService(uniqueKey))));
