Error code E0696

A function is using continue keyword incorrectly.

Erroneous code example:

#![allow(unused)]
fn main() {
fn continue_simple() {
    'b: {
        continue; // error!
    }
}
fn continue_labeled() {
    'b: {
        continue 'b; // error!
    }
}
fn continue_crossing() {
    loop {
        'b: {
            continue; // error!
        }
    }
}
}

Here we have used the continue keyword incorrectly. As we have seen above that continue pointing to a labeled block.

To fix this we have to use the labeled block properly. For example:

#![allow(unused)]
fn main() {
fn continue_simple() {
    'b: loop {
        continue ; // ok!
    }
}
fn continue_labeled() {
    'b: loop {
        continue 'b; // ok!
    }
}
fn continue_crossing() {
    loop {
        'b: loop {
            continue; // ok!
        }
    }
}
}
