Struct OwnedContainerCleanup 

pub struct OwnedContainerCleanup { /* private fields */ }

Retains the atomically acquired child identity and exclusive wait obligation.

No other thread/handler may reap this child or close its private pidfd. Explicit waits are bounded; Drop cancels and waits and can block indefinitely on an uninterruptible child or persistent inability to observe its exit. Such failures require outer process supervision, never a detached reaper.

Implementations

impl OwnedContainerCleanup

pub fn child_pid(&self) -> Pid

The original PID, for diagnostics only; do not signal or reap it separately.

pub fn observation(&self) -> ChildCleanupObservation

The last actual observation; a timeout does not fabricate a wait status.

pub fn last_error(&self) -> Option<Errno>

The most recent cleanup error, retained even after later physical exit.

pub fn wait_until(&mut self, deadline: Instant) -> ChildCleanupObservation

Observes the actual child until the absolute deadline, retaining ownership.

pub fn cancel_and_wait_until( &mut self, deadline: Instant, ) -> ChildCleanupObservation

Sends cancellation through the held pidfd, then observes until the deadline. ESRCH alone is not evidence of termination. Errors retain this owner.

Trait Implementations

impl Debug for OwnedContainerCleanup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for OwnedContainerCleanup

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
