Structures for interpreting slices of variable length as arrays.
ExactSlice for representing slices known to have
either exactly or at least some compile-time-known number of values.
This is useful when dealing with a slice whose length you expect to be exactly or at least some particular length; rather than making runtime checks on each access, you can check the length once and access values freely with no copying.
let slice = &[1, 2, 3, 4, 5, 6]; let minslice: &MinSlice<_, 3> = MinSlice::from_slice(slice).unwrap(); assert_eq!(minslice.tail.len(), 3); assert_eq!(minslice.head, 1); assert_eq!(minslice.tail, 6);
