Struct StatelessEventHandler

pub struct StatelessEventHandler<'a, A> { /* private fields */ }

An event handler which manages a simple closure that receives no state except the event argument. The closure is executed every time an event is received.

Type Parameters

• A: The type of event arguments accepted by this handler.

Example

use concurrent_event::Event;
use concurrent_event::handler::StatelessEventHandler;

let mut ev = Event::<&str, StatelessEventHandler<&str>>::new();
let handler = StatelessEventHandler::new(|arg: &str| println!("{}", arg));
ev.add_handler(handler);
ev.emit("Hello World!");

Implementations

impl<'a, A> StatelessEventHandler<'a, A>

pub fn new(f: impl Fn(A) + Send + 'a) -> StatelessEventHandler<'a, A>

Creates a new stateless event handler from a closure.

Parameters

• f: A closure which is executed every time an event is received. It consumes the event argument.
