rustHow to zip multiple iterators in Rust?
Zipping multiple iterators in Rust can be done using the zip()
method from the Iterator
trait. This method takes two or more iterators and returns a new iterator of tuples, where the first element of the tuple is from the first iterator, the second element from the second iterator, and so on.
Example code
let a = [1, 2, 3];
let b = [4, 5, 6];
let zipped = a.iter().zip(b.iter());
for t in zipped {
println!("{:?}", t);
}
Output example
(1, 4)
(2, 5)
(3, 6)
Code explanation
let a = [1, 2, 3];
: creates an array of integerslet b = [4, 5, 6];
: creates another array of integerslet zipped = a.iter().zip(b.iter());
: creates a new iterator of tuples by zipping the two iteratorsfor t in zipped {
: iterates over the zipped iteratorprintln!("{:?}", t);
: prints the tuple
