Struct critical_section::RestoreState
source · pub struct RestoreState(/* private fields */);
Expand description
Opaque “restore state”.
Implementations use this to “carry over” information between acquiring and releasing a critical section. For example, when nesting two critical sections of an implementation that disables interrupts globally, acquiring the inner one won’t disable the interrupts since they’re already disabled. The impl would use the restore state to “tell” the corresponding release that it does not have to reenable interrupts yet, only the outer release should do so.
User code uses RestoreState
opaquely, critical section implementations
use RawRestoreState
so that they can use the inner value.
