# sequentiallyConsistent

A sequentially consistent store performs a releasing store and
also guarantees that it and all other sequentially consistent
atomic operations (loads, stores, updates) appear to be executed
in a single, total sequential ordering.

```
static var sequentiallyConsistent: AtomicStoreOrdering { get }
```

## Discussion

This value corresponds to `std::memory_order_seq_cst` in C++.
