/// Throttle changing of a `Signal` value.
///
/// Use `*_local` variants for values that are not `Send + Sync`.
///
/// ## Demo
///
/// [Link to Demo](https://github.com/Synphonyte/leptos-use/tree/main/examples/signal_throttled)
///
/// ## Usage
///
/// ```
/// # use leptos::prelude::*;
/// # use leptos_use::{signal_throttled, signal_throttled_local};
/// # use std::cell::RefCell;
/// #
/// # #[component]
/// # fn Demo() -> impl IntoView {
/// 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);
/// #
/// # view! { }
/// # }
/// ```
///
/// ### Options
///
/// The usual throttle options `leading` and `trailing` are available.
///
/// ```
/// # use leptos::prelude::*;
/// # use leptos_use::{signal_throttled_with_options, signal_throttled_local_with_options, ThrottleOptions};
/// # use std::cell::RefCell;
/// #
/// # #[component]
/// # fn Demo() -> impl IntoView {
/// 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)
/// );
/// #
/// # view! { }
/// # }
/// ```

/// ## 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.
