BloombergLP::bdlb::Variant7::operator=

Assign to this object the type and value currently held by the specified rhs object, and return a reference providing modifiable access to this object. The value currently held by this variant (if any) is destroyed if that value's type is not the same as the type held by the rhs object. The contents of rhs are either move‐inserted into or move‐assigned to this object with rhs left in a valid but unspecified state.
