rustHow to loop iterator in Rust
Looping over an iterator in Rust is done using the for loop. This loop will iterate over each element in the iterator and execute the code block within the loop.
let v = vec![1, 2, 3];
for i in v {
println!("{}", i);
}
Output example
1
2
3
The code above creates a vector v with three elements and then iterates over each element in the vector using the for loop. The code block within the loop prints out the value of the element.
Code explanation
let v = vec![1, 2, 3];: creates a vectorvwith three elementsfor i in v {: starts theforloop, which will iterate over each element in the vectorvprintln!("{}", i);: prints out the value of the element}: ends theforloop
