There is a new edition of the book and this is an old link.
Rust has three kinds of loops:
loop
,while
, andfor
. Theloop
keyword tells Rust to execute a block of code over and over again forever or until you explicitly tell it to stop.while
loops evaluate a block of code until a condition ceases to be true. Afor
loop executes some code for each item in a collection.
loop {
println!("again!");
}
let mut number = 3;
while number != 0 {
println!("{number}!");
number = number - 1;
}
let a = [10, 20, 30, 40, 50];
for element in a.iter() {
println!("the value is: {element}");
}
