Zip<T>: From<U>,
Zip<T>: Iterator,
An iterator that generalizes .zip() and allows running multiple iterators in lockstep.
The iterator Zip<(I, J, ..., M)> is formed from a tuple of iterators (or values that
implement IntoIterator) and yields elements
until any of the subiterators yields None.
The iterator element type is a tuple like like (A, B, ..., E) where A to E are the
element types of the subiterator.
Note: The result of this macro is a value of a named type (Zip<(I, J, ..)> of each component iterator I, J, ...) if each component iterator is
nameable.
Prefer izip!() over multizip for the performance benefits of using the
standard library .zip(). Prefer multizip if a nameable type is needed.
