Struct AtomicOnceCellArray 

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

A fixed-size array with capacity determined at run-time. The elements of the array are uninitialized. Elements may be initialized with set and then retrieved as a reference with get. Calling set is thread-safe. The array will panic if the capacity is exceeded, or the index is out of range, or the set function is called more than once on an index when T is not zero-sized. The array will only drop initialized elements.

Guarantees

• The array will not allocate if capacity is 0 or if T is zero-sized.
• The allocated memory will not be default initialized.
• Elements initialized by set are immutable.
• The synchronization is lock-free.

Zero-sized Types

When T is zero-sized, the array does not track individual indices and instead only maintains a count of how many instances of T have been set in the array. On drop, the array will drop that many instances of T. The array will panic if the number of calls to set exceeds the capacity.
