# Error code E0267

A loop keyword (`break` or `continue`) was used inside a closure but outside of any loop.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    let w = || { break; }; // error: `break` inside of a closure
    }

`break` and `continue` keywords can be used as normal inside closures as long as they are also contained within a loop. To halt the execution of a closure you should instead use a return statement. Example:

    #![allow(unused)]
    fn main() {
    let w = || {
        for _ in 0..10 {
            break;
        }
    };

    w();
    }
