This iterator yields n successive non-overlapping mutable 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. The nth yielded segment does not attempt any further splits, and extends to the front of the bit-slice.
It is created by the BitSlice::rsplitn_mut method.
This iterator marks all yielded bit-slices as ::Aliased.
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.
