Panic stops the app when using FuturesUnordered

[arya_helen]

Hello everyone, this topic is related to this one Tokio: number of concurrent tasks - #2 by alice

When a task paniked the application stops working, is there a way, when a panic happens to keep the other tasks running without exit the whole application? (like tokio::spawn)

You can use FutureExt::catch_unwind to create a future that converts panics inside into a result. You can either use it on the future before inserting it, or on the future returned by next() like this:

let res = futs.next().catch_unwind().await;
