Enum ChildState 

pub enum ChildState {
    Gone,
    Unknown,
}

Whether the child process from the interrupted run has been confirmed gone.

A separate type rather than a bool because the two values are not interchangeable at a call site: passing the wrong one silently authorises a duplicate run, which is the exact failure recovery is meant to avoid.

Variants

Gone

The process is known to be gone: the Tower watched it exit, or checked and it was not there.

Unknown

Nobody has checked, or the check was inconclusive.
