Function zip_eq 

Source 
pub fn zip_eq<I, J>(
    i: I,
    j: J,
) -> ZipEq<<I as IntoIterator>::IntoIter, <J as IntoIterator>::IntoIter>
where
    I: IntoIterator,
    J: IntoIterator,
Expand description

Iterate i and j in lock step.

Panics if the iterators are not of the same length.

IntoIterator enabled version of Itertools::zip_eq.

use itertools::zip_eq;

let data = [1, 2, 3, 4, 5];
for (a, b) in zip_eq(&data[..data.len() - 1], &data[1..]) {
    /* loop body */
}
