pub struct WorkGuard<'a> { /* private fields */ }Expand description
RAII registration for one in-flight operation.
Why: see WorkerLiveness::track — drop-driven release is what makes the
gauge correct across the ? and panic paths that a wedge actually travels.
What: releases its slot (or decrements overflow) on drop.
Test: guard_releases_slot_on_drop, guard_releases_slot_on_panic.
