Crate parking_lot

This library provides implementations of Mutex, RwLock, Condvar and Once that are smaller, faster and more flexible than those in the Rust standard library. It also provides a ReentrantMutex type.

Re-exports

• pub use ::lock_api;

Modules

• deadlock
  [Experimental] Deadlock detection

Structs

• ArcMutexGuard
  An RAII mutex guard returned by the Arc locking operations on Mutex.
• ArcReentrantMutexGuard
  An RAII mutex guard returned by the Arc locking operations on ReentrantMutex.
• ArcRwLockReadGuard
  An RAII rwlock guard returned by the Arc locking operations on RwLock.
• ArcRwLockUpgradableReadGuard
  An RAII rwlock guard returned by the Arc locking operations on RwLock. This is similar to the RwLockUpgradableReadGuard struct, except instead of using a reference to unlock the RwLock it uses an Arc<RwLock>. This has several advantages, most notably that it has an 'static lifetime.
• ArcRwLockWriteGuard
  An RAII rwlock guard returned by the Arc locking operations on RwLock. This is similar to the RwLockWriteGuard struct, except instead of using a reference to unlock the RwLock it uses an Arc<RwLock>. This has several advantages, most notably that it has an 'static lifetime.
• Condvar
  A Condition Variable
• Once
  A synchronization primitive which can be used to run a one-time initialization. Useful for one-time initialization for globals, FFI or related functionality.
• RawFairMutex
  Raw fair mutex type backed by the parking lot.
• RawMutex
  Raw mutex type backed by the parking lot.
• RawRwLock
  Raw reader-writer lock type backed by the parking lot.
• RawThreadId
  Implementation of the GetThreadId trait for lock_api::ReentrantMutex.
• WaitTimeoutResult
  A type indicating whether a timed wait on a condition variable returned due to a time out or not.

Enums

• OnceState
  Current state of a Once.

Functions

• const_fair_mutex
  Creates a new fair mutex in an unlocked state ready for use.
• const_mutex
  Creates a new mutex in an unlocked state ready for use.
• const_reentrant_mutex
  Creates a new reentrant mutex in an unlocked state ready for use.
• const_rwlock
  Creates a new instance of an RwLock<T> which is unlocked.

Type Aliases

• FairMutex
  A mutual exclusive primitive that is always fair, useful for protecting shared data
• FairMutexGuard
  An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.
• MappedFairMutexGuard
  An RAII mutex guard returned by FairMutexGuard::map, which can point to a subfield of the protected data.
• MappedMutexGuard
  An RAII mutex guard returned by MutexGuard::map, which can point to a subfield of the protected data.
• MappedReentrantMutexGuard
  An RAII mutex guard returned by ReentrantMutexGuard::map, which can point to a subfield of the protected data.
• MappedRwLockReadGuard
  An RAII read lock guard returned by RwLockReadGuard::map, which can point to a subfield of the protected data.
• MappedRwLockWriteGuard
  An RAII write lock guard returned by RwLockWriteGuard::map, which can point to a subfield of the protected data.
• Mutex
  A mutual exclusion primitive useful for protecting shared data
• MutexGuard
  An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.
• ReentrantMutex
  A mutex which can be recursively locked by a single thread.
• ReentrantMutexGuard
  An RAII implementation of a “scoped lock” of a reentrant mutex. When this structure is dropped (falls out of scope), the lock will be unlocked.
• RwLock
  A reader-writer lock
• RwLockReadGuard
  RAII structure used to release the shared read access of a lock when dropped.
• RwLockUpgradableReadGuard
  RAII structure used to release the upgradable read access of a lock when dropped.
• RwLockWriteGuard
  RAII structure used to release the exclusive write access of a lock when dropped.
