BloombergLP::bdljsn::Json::operator=

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).
