What is the Scala equivalent of F#'s async workflows?
For example, how would following F# snippet translate to idiomatic Scala?
open System.Net
open Microsoft.FSharp.Control.WebExtensions
let urlList = [ "Microsoft.com", "http://www.microsoft.com/"
"MSDN", "http://msdn.microsoft.com/"
"Bing", "http://www.bing.com"
]
let fetchAsync(name, url:string) =
async {
try
let uri = new System.Uri(url)
let webClient = new WebClient()
let! html = webClient.AsyncDownloadString(uri)
printfn "Read %d characters for %s" html.Length name
with
| ex -> printfn "%s" (ex.Message);
}
let runAll() =
urlList
|> Seq.map fetchAsync
|> Async.Parallel
|> Async.RunSynchronously
|> ignore
runAll()
