### How do I use egui with `async`?
If you call `.await` in your GUI code, the UI will freeze, with is very bad UX. Instead, keep the GUI thread non-blocking and communicate with any concurrent tasks (`async` tasks or other threads) with something like:
If you call `.await` in your GUI code, the UI will freeze, which is very bad UX. Instead, keep the GUI thread non-blocking and communicate with any concurrent tasks (`async` tasks or other threads) with something like:
* Channels (e.g. [`std::sync::mpsc::channel`](https://doc.rust-lang.org/std/sync/mpsc/fn.channel.html)). Make sure to use [`try_recv`](https://doc.rust-lang.org/std/sync/mpsc/struct.Receiver.html#method.try_recv) so you don't block the gui thread!
* `Arc<Mutex<Value>>` (background thread sets a value; GUI thread reads it)
* [`poll_promise::Promise`](https://docs.rs/poll-promise) (example: [`examples/download_image/`](https://github.com/emilk/egui/blob/master/examples/download_image/))
