Assign to this object the value of the specified `rhs` object, and return a reference providing modifiable access to this object. The contents of `rhs` are moved (in constant time) to this `Json` object if `allocator() == rhs.allocator()`; otherwise, they are copied. `rhs` is left in a valid but unspecified state. The value currently held by this object (if any) is destroyed if that value's type is not `bsl::string`. This function does not participate in overload resolution unless the specified `t_STRING_TYPE` is `bsl::string`. The behavior is undefined unless `rhs` is valid UTF‐8 (see `bdlde::Utf8Util::isValid`).
