Object Safety

This trait is not object safe.

Implementations on Foreign Types

impl<T> SignalWatch for RwSignal<T>

fn watch(&self, f: impl Fn(&Self::Value) + 'static) -> Box<dyn FnOnce()>

Listens for RwSignal changes and is not executed immediately

Usage

use leptos::*;
use thaw::*;

let count = create_rw_signal(0);
let stop = count.watch(|count| {
    assert_eq!(count, &1);
});

count.set(1); // assert_eq!(count, &1);

stop(); // stop watching

count.set(2); // nothing happens

type Value = T
