Struct PriorityInheritance 

pub struct PriorityInheritance { /* private fields */ }

Priority-inheritance protocol core (RT-CORBA §5.6).

Holds the base priority of a lock owner plus the priorities of all waiters currently blocked on this lock. effective is the maximum — the priority at which the owner should run while it holds the lock.

Implementations

impl PriorityInheritance

pub fn new(base: Priority) -> Self

New state for an owner with the given base priority, without waiters.

pub fn base(&self) -> Priority

The owner’s base priority.

pub fn effective(&self) -> Priority

Effective priority: max(base, highest waiter priority).

pub fn on_block(&mut self, waiter: Priority) -> Priority

A waiter now blocks on the lock. Returns the (possibly raised) effective priority.

pub fn on_unblock(&mut self, waiter: Priority) -> Priority

A waiter was served/cancelled — its priority drops out of the inheritance. Returns the new effective priority.

pub fn waiter_count(&self) -> usize

Number of currently blocked waiters.
