Function alias::one
[−]
[src]
pub fn one<'a, T: Copy>(data: &'a mut T) -> &'a Cell<T>
Allow the mutable reference data
to be mutated while aliased.
Examples
let mut x = 0; let y = alias::one(&mut x); let z = y; // now we can read/write through multiple references z.set(10); y.set(y.get() + 2); assert_eq!(z.get(), 12);
