Обычно вместо этого делают интерфейс
struct IServerListener {
virtual onReadCb(std::string &&) = 0;
virtual onWriteCb(boost::system::error_code &err) = 0;
};

не увлекайтесь rvalue, копирование 20 байт быстрая операция, а вот передать константную строку вы уже не сможете

по-моему в колбеке const

| #include <atomic> | ||

constexpr int BUFFER_LENGTH = 1024; забудьте про макросы и define
| #include <atomic> | ||
|

| #define BUFFER_LENGTH 1024 | ||
| #define END_STR "\r\n" |
