[[Rust]]
[[A scope block is an expression]]
[[Loop labels]]
A loop can return values, it is an expression. Thus it can be used in an assignment as well.
It is possible to `return ` but that would exit the function, instead we can also `break expression;` and return a value just from the loop by breaking it with a value (as we would normally write a `return`).
```rust
fn main() {
let mut counter = 0;
let result = loop {
counter += 1;
if counter == 10 {
break counter * 2;
}
};
println!("The result is {result}");
}
```
