AP>Помогите, пожалуйста, понять идею реализации.

struct protocol_error : public virtual run_error
{
    typedef struct common_error;
    typedef struct timeout_error;
    typedef struct crc_error;
};

struct protocol_error::common_error : public virtual protocol_error {};
struct protocol_error::timeout_error : public virtual  protocol_error {};
struct protocol_error::crc_error : public virtual protocol_error {};
