Function sycamore_reactive::untrack

source · [−]
pub fn untrack<T>(f: impl FnOnce() -> T) -> T
Expand description

Run the passed closure inside an untracked dependency scope.

See also ReadSignal::get_untracked().

Example

let state = create_signal(cx, 1);
let double = create_memo(cx, || untrack(|| *state.get() * 2));
//                              ^^^^^^^
assert_eq!(*double.get(), 2);

state.set(2);
// double value should still be old value because state was untracked
assert_eq!(*double.get(), 2);
