Struct EventEmitter

pub struct EventEmitter<TEvent> { /* private fields */ }

Basic event emitter

Example:

use alone_ee::EventEmitter;
let mut ee: EventEmitter<u32> = EventEmitter::new();
ee.on(Box::new(|event| {
   println!("hello {}", event);
   Ok(())
}));
ee.on(Box::new(|event| {
   println!("world {}", event);
   Ok(())
}));
ee.emit(&22).unwrap();
