pub fn chain<I, J>(
i: I,
j: J
) -> Chain<<I as IntoIterator>::IntoIter, <J as IntoIterator>::IntoIter>where
I: IntoIterator,
J: IntoIterator<Item = I::Item>,
Expand description
Takes two iterables and creates a new iterator over both in sequence.
IntoIterator
enabled version of Iterator::chain
.
Example
use itertools::chain;
let mut result:Vec<i32> = Vec::new();
for element in chain(&[1, 2, 3], &[4]) {
result.push(*element);
}
assert_eq!(result, vec![1, 2, 3, 4]);
