[−][src]Struct events_emitter::EventEmitter

pub struct EventEmitter<T> {
    pub listeners: Vec<Listener<T>>,
}

Fields

listeners: Vec<Listener<T>>

Methods

impl<T> EventEmitter<T>[src]

pub fn new() -> Self[src]

Create an instance.

Create event loop bus.

example

let events = EventEmitter::new();

pub fn on(&mut self, name: &str, listener: fn(_: &T))[src]

Binding listener.

Binding event.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{}", x) });

pub fn emit(&mut self, name: &str, value: &T)[src]

Trigger listener.

Push event.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{:?}", x) });
events.emit("hello", "word");

pub fn event_names(&mut self) -> Vec<&str>[src]

Returns an array of event names for registered listeners.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{}", x) });
println!("{:?}", events.event_names());

pub fn listener_count(&mut self, name: &str) -> u8[src]

Returns the number of event listeners being listened to.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{}", x) });
println!("{:?}", events.listener_count());

pub fn once(&mut self, name: &str, listener: fn(_: &T))[src]

Add once listener

example

let events = EventEmitter::new();
events.once("hello", |x| { println!("{}", x) });

pub fn remove(&mut self, name: &str)[src]

Remove listener.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{}", x) });
events.remove("hello");

pub fn listeners(&mut self, name: &str) -> Vec<&Listener<T>>[src]

Returns the specified listener list for the binding.

example

let events = EventEmitter::new();
events.on("hello", |x| { println!("{}", x) });
events.listeners("hello");
