Function signal_throttled 

pub fn signal_throttled<S, T>(
    value: S,
    ms: impl Into<Signal<f64>> + 'static,
) -> Signal<T, SyncStorage>
where
    S: Into<Signal<T, SyncStorage>>,
    T: Send + Sync + Clone + 'static,

Throttle changing of a Signal value.

Use *_local variants for values that are not Send + Sync.

Usage

let (input, set_input) = signal("");
let throttled: Signal<&'static str> = signal_throttled(input, 1000.0);

let (input_local, set_input_local) = signal_local(RefCell::new(0));
let throttled_local: Signal<RefCell<i32>, _> = signal_throttled_local(input_local, 1000.0);

Options

The usual throttle options leading and trailing are available.

let (input, set_input) = signal("");
let throttled: Signal<&'static str> = signal_throttled_with_options(
    input,
    1000.0,
    ThrottleOptions::default().leading(false).trailing(true)
);

let (input_local, set_input_local) = signal_local(RefCell::new(0));
let throttled_local: Signal<RefCell<i32>, _> = signal_throttled_local_with_options(
    input_local,
    1000.0,
    ThrottleOptions::default().leading(false).trailing(true)
);

Server-Side Rendering

Make sure you follow the instructions in Server-Side Rendering.

Internally this uses setTimeout which is not supported on the server. So usually a throttled signal on the server will simply be ignored.
