Struct AtomicOnceCell 

pub struct AtomicOnceCell<T> { /* private fields */ }

A thread-safe container that does not require default initialization. The cell may be initialized with set and then retrieved as a reference with get. Calling set is thread-safe. The cell will panic if the set function is called more than once. The cell will only drop initialized elements.

Guarantees

• The allocated memory will not be default initialized.
• Elements initialized by set are immutable.
• The synchronization is lock-free.
