:relfileprefix: ../../
:mrdocs:

Modify this allocator to use the same mechanism as the specified `rhs` allocator and return a modifiable reference to this object. Note that `bsl::allocator` objects should never be assigned at runtime, but, in the absence of `if constexpr`, such assignments can sometimes be found legitimately in dead branches (branches that are never taken at runtime) within function templates; ideally, such code would be replaced by more sophisticated metaprogramming that avoided calls to this operator entirely. Invoking this assignment will result in a review error unless `rhs == *this`, i.e., when the assignment would be a no‐op. In the future, the review error may be replaced with an a hard assertion failure.
