Module alloc::sync

Thread-safe reference-counting pointers.

See the Arc<T> documentation for more details.

Note: This module is only available on platforms that support atomic loads and stores of pointers. This may be detected at compile time using #[cfg(target_has_atomic = "ptr")].

Structs

• Arc
  A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.
• Weak
  Weak is a version of Arc that holds a non-owning reference to the managed allocation. The allocation is accessed by calling upgrade on the Weak pointer, which returns an Option<Arc<T>>.
