rmw_request_id_t Struct Reference

#include <rmw_entity.h>

Data Fields
int64_t	sequence_number
int8_t	writer_guid [16]

Detailed Description

Identity of one service request — upstream rmw_request_id_t, field for field.

sequence_number is the number the CLIENT assigned to the request, which together with writer_guid makes the pair unique across clients. It is not the backend's reply-correlation token (take_request_with_info's seq_out), and the two need not agree.
