Implementations

impl Reaper

pub(crate) fn new() -> Self

This makes it so only one thread can reap at once.

pub(crate) async fn reap(&'static self, lock: Lock) -> !

Reap zombie processes forever.

pub(crate) fn register(&'static self, child: Child) -> Result<ChildGuard>

Register a child into this reaper.

pub(crate) async fn status( &'static self, child: &Mutex<ChildGuard>, ) -> Result<ExitStatus>

Wait for the inner child to complete.

pub(crate) fn has_zombies(&'static self) -> bool

Do we have any registered zombie processes?
