Function alias::slice

pub fn slice<'a, T: Copy>(data: &'a mut [T]) -> &'a [Cell<T>]

Allow the contents of the mutable slice data to be mutated while aliased.

Examples

let mut x = [0, 0, 0, 0];

let y = alias::slice(&mut x);
let z = y;

// now we can read/write through multiple references
for i in 0..4 {
    z[i].set(10);
    y[i].set(y[i].get() + i);
}

assert_eq!(z[0].get(), 10);
assert_eq!(z[1].get(), 11);
assert_eq!(z[2].get(), 12);
assert_eq!(z[3].get(), 13);
