Module webio::event

Available on crate feature event only.

Module for listening and handling JS events from Rust.

Examples

On Click

use webio::event::EventType;
use webio::event::Click;

let document =
    web_sys::window().expect("only browser supported").document().unwrap();

let element = document.create_element("button").unwrap();
document.body().unwrap().append_child(&element).unwrap();
let mut count = 0;
let listener = Click.add_listener(&element);
element.dispatch_event(&web_sys::MouseEvent::new("click").unwrap()).unwrap();
listener.listen_next().await.unwrap();
element.dispatch_event(&web_sys::MouseEvent::new("click").unwrap()).unwrap();
listener.listen_next().await.unwrap();
element.dispatch_event(&web_sys::MouseEvent::new("click").unwrap()).unwrap();
listener.listen_next().await.unwrap();

document.remove_child(&element).unwrap();

Functions

• add_listener_raw
  Raw function for adding event listeners to JS’s event targets. This function is asynchronous and a future is returned.
• add_listener_with_async_cb_raw
  Raw function for adding event listeners to JS’s event targets, using asynchronous event listeners. This function is asynchronous and a future is returned.
• add_listener_with_sync_cb_raw
  Raw function for adding event listeners to JS’s event targets, using synchronous event listeners. However, this function is asynchronous and a future is returned.
