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;

Structs

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 Definitions

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.
