Module sync 

Synchronization primitives working across std, no-std and wasm environments.

Modules

reentrant

Re-entrant locking primitives, available in std environments.

Structs

Arc

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Lazy

A value which is initialized on the first access.

Mutex

A mutual exclusion primitive useful for protecting shared data

RwLock

A reader-writer lock which is exclusively locked for writing or shared for reading. This reader-writer lock will block threads waiting for the lock to become available. The lock can also be statically initialized or created via a RwLock::new RwLock wrapper to make spin::RwLock API compatible with std::sync::RwLock to swap

RwLockReadGuard

RAII structure used to release the shared read access of a lock when dropped.

RwLockWriteGuard

RAII structure used to release the exclusive write access of a lock when dropped.

SyncOnceCell

A cell that provides lazy one-time initialization that implements Sync and Send.

ThreadId

An opaque thread identifier.

Enums

Ordering

Atomic memory orderings

Type Aliases

AtomicBool

A boolean type which can be safely shared between threads.

AtomicU8

An integer type which can be safely shared between threads.

AtomicU32

An integer type which can be safely shared between threads.

AtomicUsize

An integer type which can be safely shared between threads.

Once

A spin-based one-time initialization cell, identical on every target.
