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]);
