Struct gloo_timers::callback::Timeout

pub struct Timeout { /* private fields */ }

A scheduled timeout.

See Timeout::new for scheduling new timeouts.

Once scheduled, you can either cancel so that it doesn’t run or forget it so that it is un-cancel-able.

Implementations

impl Timeout

pub fn new<F>(millis: u32, callback: F) -> Timeout where
    F: 'static + FnOnce(), 

Schedule a timeout to invoke callback in millis milliseconds from now.

Example

use gloo_timers::callback::Timeout;

let timeout = Timeout::new(1_000, move || {
    // Do something...
});

pub fn forget(self) -> i32

Make this timeout uncancel-able.

Returns the identifier returned by the original setTimeout call, and therefore you can still cancel the timeout by calling clearTimeout directly (perhaps via web_sys::clear_timeout_with_handle).

Example

use gloo_timers::callback::Timeout;

// We definitely want to do stuff, and aren't going to ever cancel this
// timeout.
Timeout::new(1_000, || {
    // Do stuff...
}).forget();

pub fn cancel(self) -> Closure<dyn FnMut()>

Cancel this timeout so that the callback is not invoked after the time is up.

The scheduled callback is returned.

Example

use gloo_timers::callback::Timeout;

let timeout = Timeout::new(1_000, || {
    // Do stuff...
});

// If actually we didn't want to set a timer, then cancel it.
if nevermind() {
    timeout.cancel();
}
