# Common hooks for Dioxus
|
|
|
|
This crate includes some basic useful hooks for dioxus:
|
|
|
|
- use_state
|
|
- use_ref
|
|
- use_collection
|
|
- use_task
|
|
- use_signal
|
|
|
|
## use_state
|
|
|
|
The king daddy of state hooks.
|
|
|
|
You can always use it "normally" with the `split` method:
|
|
|
|
```rust
|
|
// Normal usage:
|
|
let value = use_state(cx, || 10);
|
|
|
|
// "Classic" usage:
|
|
let (value, set_value) = use_state(cx, || 0).classic();
|
|
```
|
|
|
|
## use_ref
|
|
|
|
|
|
## use_rwlock
|
|
A multithreaded form of RwLock for use in tasks
|
|
```rust
|
|
let val = use_rwlock(cx, || 10);
|
|
use_task((), || async loop {
|
|
*val.write().unwrap() += 1;
|
|
async_std::task::delay(Duration::from_ms(1000)).await;
|
|
});
|
|
use_task((), || async loop {
|
|
*val.write().unwrap() -= 1;
|
|
async_std::task::delay(Duration::from_ms(500)).await;
|
|
});
|
|
```
|
|
|
|
## use_hashmap
|
|
Store a memoized collection with similar semantics to use_state. Comes with a bunch of utility methods to make working with collections easier. Is essentially a wrapper over the immutable hashmap in im-rc.
|
|
|
|
```rust
|
|
let todos = use_hashmap(cx, |map| map.insert("bob", "bill"));
|
|
cx.render(rsx!(
|
|
button { onclick: move |_| todos.insert("bob", "bill")
|
|
"add random todo"
|
|
}
|
|
)
|
|
|
|
```
|
|
|
|
## use_task
|
|
|
|
use_task submits a task to the dioxus task queue to be progressed during Dioxus's async event loop. The task must not return anything
|
|

## use_signal
|
