# Suspense, Async, and More
|
|
|
|
This doc goes into the design of asynchronicity in Dioxus.
|
|
|
|
|
|
## for UI elements
|
|
|
|
`suspend`-ing a future submits an &mut future to Dioxus. the future must return VNodes. the future is still waiting before the component renders, the `.await` is dropped and tried again. users will want to attach their future to a hook so the future doesn't really get dropped.
|
|
|
|
|
|
## for tasks
|
|
|
|
for more general tasks, we need some way of submitting a future or task into some sort of task system.
|
|
|
|
|
|
`use_task()` submits a future to Dioxus. the future is polled infinitely until it finishes. The caller of `use_task` may drop, pause, restart, or insert a new the task
|
|
|
|
```rust
|
|
|
|
let task = use_hook(
|
|
|| { /* */ },
|
|
|| { /* update the future if it needs to be updated */ },
|
|
|| {}
|
|
);
|
|
cx.poll_future()
|
|
// let recoil_event_loop = cx.use_task(move |_| async move {
|
|
// loop {
|
|
// let msg = receiver.await?;
|
|
// }
|
|
// });
|
|
// where suspend wraps use_task
|
|
```
