Struct RevocableGuard

Source 
pub struct RevocableGuard<'a, T> { /* private fields */ }
Expand description

A guard that allows access to a revocable object and keeps it alive.

CPUs may not sleep while holding on to RevocableGuard because it’s in atomic context holding the RCU read-side lock.

§Invariants

The RCU read-side lock is held while the guard is alive.
