DispatchLock

Struct DispatchLock 

Source
pub struct DispatchLock<'a> { /* private fields */ }
Expand description

A lock that prevents concurrent dispatching of a queue.

This lock can be acquired by calling Queue::lock_dispatch.

See the description of Queue for why you might use this.

§Example

let lib = Libwayland::open().unwrap();
let con = lib.connect_to_default_display().unwrap();
let queue = con.create_queue(c"queue name");

let lock = queue.lock_dispatch();

let thread = {
    let queue = queue.clone();
    thread::spawn(move || {
        // this dispatch will not start until the lock is dropped.
        queue.dispatch_roundtrip_blocking().unwrap();
    })
};

// this dispatch starts immediately since the lock is re-entrant
queue.dispatch_roundtrip_blocking().unwrap();

drop(lock);
thread.join().unwrap();
