Enum OwnerDeathCleanup 

pub enum OwnerDeathCleanup {
    OwnerDeathSignal,
    KillOnOwnerHandleClose,
    AlreadyContained,
    SupervisorRequired,
    Unsupported,
}

What this host installed so a child outlives its owner no longer than it should.

The variants name the guarantee, not the call that produced it. A caller deciding whether to spawn a supervisor cares that the kernel will not do the reaping for it; whether the kernel would have used a parent-death signal or a job object is not a distinction it can act on.

Variants

OwnerDeathSignal

The kernel signals this process when its owner exits.

KillOnOwnerHandleClose

This process belongs to a container the kernel destroys with its owner.

AlreadyContained

This process was already in such a container, installed by someone else.

SupervisorRequired

The host offers no kernel mechanism; a supervisor must do the reaping.

Unsupported

The host offers nothing and no supervisor contract is defined here.
