Synchronization objects used by Starnix
Macros§
- lock_
ordering - This macro takes a definition of the lock ordering graph in the form of lock_ordering!{ Unlocked -> A, A -> B, Unlocked -> C, }
Structs§
- Atomic
Monotonic Instant - An atomic wrapper around
zx::MonotonicInstant. - CondVar
- A Condition Variable that is compatible with both standard Mutex and LockDepMutex in Starnix.
- Dynamic
Lock DepMutex - A Mutex that dynamically enforces lock ordering at runtime, without using types for levels.
- Dynamic
Lock DepRw Lock - An RwLock that dynamically enforces lock ordering at runtime, without using types for levels.
- Event
Wait Guard - A guard object to enforce that clients call
begin_waitbeforeblock_until. - Interruptible
Event - A blocking object that can either be notified normally or interrupted
- Lock
DepGuard - Lock
DepMutex - A Mutex that dynamically enforces lock ordering at runtime using types for levels.
- Lock
DepRead Guard - Lock
DepRw Lock - An RwLock that dynamically enforces lock ordering at runtime using types for levels.
- Lock
DepWrite Guard - Lock
Level Token - A token that represents a lock level being held for lockdep purposes. This does not actually hold a lock, but updates the lockdep state as if it did.
- Mapped
Lock DepGuard - Mapped
Lock DepRead Guard - Mapped
Lock DepWrite Guard - Port
Event - A wrapper around a
zx::Portthat optimizes for the case where events are signaled within a process. - RwSeq
Lock - A sequence lock that combines a standard lock (like a Mutex) with a sequence counter. This allows lock-free concurrent reads by spinning if a write is in progress, while still enforcing mutually exclusive writes.
- RwSeq
Lock Guard - A guard that manages the sequence counter and wraps the underlying lock guard.
- Thread
Affinity - A synchronization primitive that tracks thread affinity.
- Thread
Affinity Guard - Wait
Token - A token that proves the caller is allowed to access the inner guard. Its field is private, so it can only be constructed within this crate.

Traits§
- Async
Unlockable - A trait for lock guards that can be temporarily unlocked asynchronously. This is useful for performing async operations while holding a lock, without causing deadlocks or holding the lock for an extended period.
- Lock
Level - A trait for types that represent a lock level in the lock dependency tracker.
- Mutex
Like - A generic mutex for the ordered_lock operations.
- RwLock
Like - A generic rwlock for the ordered_lock operations.
- Waitable
Mutex Guard
Functions§
- allow_
subclass - A token that allows the next lock acquisition of the same level as the currently maximal held lock to use an incremented subclass. Allows subclassing of the currently maximal held lock.
- assert_
lock_ level - Asserts that the current thread can acquire locks at level
L. Returns a token that, when held, forces subsequent locks to be afterL. - ordered_
lock - Lock
m1andm2in a consistent order (using the memory address of m1 and m2 and returns the associated guard. This ensure thatordered_lock(m1, m2)andordered_lock(m2, m1)will not deadlock. - ordered_
lock_ vec - Acquires multiple mutexes in a consistent order based on their memory addresses. This helps prevent deadlocks.
- ordered_
read_ lock - Lock
r1andr2in a consistent order (using the memory address of r1 and r2) for reading. - ordered_
read_ lock_ vec - Acquires multiple rwlocks in a consistent order based on their memory addresses for reading.
- ordered_
write_ lock - Lock
r1andr2in a consistent order (using the memory address of r1 and r2) for writing. - ordered_
write_ lock_ vec - Acquires multiple rwlocks in a consistent order based on their memory addresses for writing.
