Struct RequestId 

pub struct RequestId {
    pub writer_guid: [u8; 16],
    pub sequence_number: i64,
}

Identity of one service request — rclrs’s RequestId, upstream’s rmw_request_id_t.

sequence_number is the number the CLIENT assigned to the request, which is what makes (writer_guid, sequence_number) unique across clients. It is not necessarily the token a backend replies against: the zenoh backend replies against a local reply-slot index, and that index is never reported here.

Fields

writer_guid: [u8; 16]

The requesting client’s GID. On zenoh this is XXH3-128 of the client’s liveliness keyexpr — rmw_zenoh_cpp’s derivation, so it equals the gid that client’s get_gid reports, ours or a stock peer’s.

sequence_number: i64

The client-assigned sequence number of this request.
