[−][src]Trait mark_last::MarkLastIterator
Required methods
pub fn mark_last(self) -> MarkLast<I>ⓘ
[src]
Creates an iterator which gives the next value as well as a boolean indicating if this is the last value of the iterator.
The iterator returned yields pairs (b, val)
, where b
is true if this is the last value
and val
is the value returned by the iterator.
Examples
let in_data = vec![1, 2, 3, 5, 99]; let out_data: Vec<_> = in_data.into_iter().mark_last().collect(); assert_eq!( out_data, vec![(false, 1), (false, 2), (false, 3), (false, 5), (true, 99)] );
