README
RcuCell
A lockless rcu cell implementation that can be used safely in multithread context.
Features
-
Support multi-thread read and write operations.
-
The read operation would not block other read operation.
-
The read operation is something like Arc::clone
-
The write operation is something like Atomic Swap.
-
The write operation would block all read operations.
-
The RcuCell could contain no data
-
Could be compiled with no_std
Usage
use rcu_cell::RcuCell;
use std::sync::Arc;
let t = Arc::new(RcuCell::new(10));
let t1 = t.clone();
let t2 = t.clone();
let d1 = t1.take().unwrap();
assert_eq!(*d1, 10);
assert_eq!(t1.read(), None);
let d2 = t2.write(42);
assert!(d2.is_none());
let d3 = t2.read().unwrap();
assert_eq!(*d3, 42);
