Shared Bit-Slice Reverse Splitting

This iterator yields successive non-overlapping segments of a bit-slice, separated by bits that match a predicate function. Splitting advances one segment at a time, starting at the end of the bit-slice.

The matched bit is not included in the yielded segment.

It is created by the BitSlice::rsplit method.

Original

slice::RSplit

API Differences

The predicate function receives both the index within the bit-slice, as well as the bit value, in order to allow the predicate to have more than one bit of information when splitting.

Examples

use bitvec::prelude::*;

let bits = bits![0, 0, 0, 1, 1, 1, 0, 1];
let mut split = bits.rsplit(|idx, _bit| idx % 3 == 2);

assert_eq!(split.next().unwrap(), bits![0, 1]);
assert_eq!(split.next().unwrap(), bits![1; 2]);
assert_eq!(split.next().unwrap(), bits![0; 2]);
assert!(split.next().is_none());
