Struct LoopExpr

Source
#[repr(C)]
pub struct LoopExpr<'ast> { /* private fields */ }
Expand description

An unconditional loop expression

    //      vvvvvv A loop expression
    let _ = loop {
        break 3;
    //  ^^^^^^^ A break expression targeting the loop and returning a value
    };

//  vvvvvvvvvvvvvvvvvv An infinite loop
    'infinite: loop {};
//  ^^^^^^^^^       ^^ A block expression as the loop body expression
//      |
//      An optional label to be targeted by break and continue expressions
