:mrdocs:

Swap the contents of the specified `lhs` of the parameterized `LHS_TYPE` with those of the specified `rhs` of the parameterized `RHS_TYPE`. Note that, if `LHS_TYPE` and `RHS_TYPE` are the same type and that type has the bit‐wise moveable trait but does not use `bslma` allocators, the swap can be performed using a three‐way bit‐wise move.
