Struct RSplit

#[must_use = "iterators are lazy and do nothing unless consumed"]
pub struct RSplit<'a, T: 'a, P>
where
    P: FnMut(&T) -> bool, { pub(in ::slice::iter) inner: Split<'a, T, P> }

An iterator over subslices separated by elements that match a predicate function, starting from the end of the slice.

This struct is created by the rsplit method on slices.

Example

let slice = [11, 22, 33, 0, 44, 55];
let mut iter = slice.rsplit(|num| *num == 0);
assert_eq!(iter.next(), Some(&[44, 55][..]));
assert_eq!(iter.next(), Some(&[11, 22, 33][..]));
assert_eq!(iter.next(), None);

Fields

inner: Split<'a, T, P>
