Trait Implementations

impl TreeReaper for UnixReaper

fn kill_tree(&self) -> Result<()>

INVARIANT: only ever called while the Child is still owned and un-reaped, so the pid is either live or a zombie — reserved either way, and never reusable by another process. Killing after a wait would be a pid-reuse bug: the number could by then name someone else’s process, and the negation someone else’s group.

const ADOPTION_IS_ATOMIC: bool = true

Whether a descendant can escape between spawn and adoption.

fn adopt(&self, child: &Child) -> Result<()>

Take ownership of child and everything it goes on to spawn.
