RcuCell

A lockless rcu cell implementation that can be used safely in multithread context.

Features

  • The write operation would not block the read operation.
  • The write operation would "block" the write operation.
  • The RcuCell could contain no data

Usage

   fn single_thread() {
        let t = RcuCell::new(Some(10));
        let x = t.read();
        let y = t.read();
        t.try_lock().unwrap().update(None);
        let z = t.read();
        let a = z.clone();
        drop(t); // t can be dropped before reader
        assert_eq!(x.map(|v| *v), Some(10));
        assert_eq!(y.map(|v| *v), Some(10));
        assert_eq!(z.map(|v| *v), None);
        assert_eq!(a.map(|v| *v), None);
    }
