disjoint-borrow

Disjoint borrows of slices.

Provides the DisjointSlice type, allowing disjoint borrows over slices by adding runtime checks. Immutable borrows are allowed to intersect with other immutable borrows, while mutable borrows may not intersect with any borrows.

Borrow tracking is implemented as type-level list. This has the advantage that no allocation is necessary, but also limits the number of disjoint borrows to a compile-time constant.

No-std compatible.

Example

use disjoint_borrow::DisjointSlice;

let mut array = [1, 2, 3, 4, 5];
let mut ds = DisjointSlice::new(&mut array);
let (mut ds, mut a) = ds.get_mut(0..2);
let (_, mut b) = ds.get_mut(3..5);

a[0] *= -1;
b[1] *= -1;

assert_eq!(a, &[-1, 2]);
assert_eq!(b, &[4, -5]);
