1) Atomically assigns the
desired value to the atomic variable. Equivalent to store(desired). The volatile-qualified version is deprecated if std::atomic<T>::is_always_lock_free is false. (since C++20)2) Atomic variables are not CopyAssignable.
Parameters
| desired | - | value to assign |
Return value
desired.
Notes
Unlike most assignment operators, the assignment operators for atomic types do not return a reference to their left-hand arguments. They return a copy of the stored value instead.
