for
The for
loop iterates over ranges of values or the items in a collection:
fn main() { for x in 1..5 { println!("x: {x}"); } for elem in [1, 2, 3, 4, 5] { println!("elem: {elem}"); } }

loops use a concept called "iterators" to handle iterating over different kinds of ranges/collections. Iterators will be discussed in more detail later. for
