Enum Signal 

pub enum Signal {
    Break,
    Continue,
    Return,
}

Flow control signal returned by exec_stmts.

Used to propagate break, continue, and return through nested block calls. Loop implementations catch Break/Continue; function call implementation catches Return. Uncaught signals at the top level are reported as errors.

Variants

Break

break — exit the innermost enclosing loop immediately.

Continue

continue — skip the rest of the current iteration and advance to the next.

Return

return inside a named function — carries no value (outputs are read from env).
