The engine’s counts, as BACnetRouter::counters reads them. Counts of what the router dropped, sent and was refused. They saturate, never change a decision, and name no peer. The table’s own counts are Table::claim_counters.

It is #[non_exhaustive], so a new count isn’t a breaking change. Outside this crate, build one from Counters::default() and set its fields.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

address_length_drops: u64

Frames refused because the link source, the DLEN or the SLEN was past MAX_MAC_LEN (#1141, #1198).

global_broadcast_dadr_drops: u64

Frames dropped for a DADR beside DNET 0xFFFF (#1379).

broadcast_pdu_type_drops: u64

Broadcasts dropped for carrying an APDU other than an Unconfirmed-Request (#1491).

group_dadr_drops: u64

Frames dropped for a DADR that is a group address on its delivery port: an APDU other than an Unconfirmed-Request, a network message, or anything for a Group::Refuse address (#1504, #1677). An Unconfirmed-Request sent as the port’s broadcast instead isn’t counted.

malformed: u64

Frames that didn’t parse as an NPDU for any other reason.

bad_messages: u64

Network messages whose data or addressing the router refused.

unknown_port: u64

Frames that came on a port the router doesn’t have, or whose route names one.

hop_count_drops: u64

Relays not sent because the hop count had run out.

denied: u64

Protected network messages Host::authorize refused.

unroutable_rejects: u64

Received rejects that were neither for this router nor routable.

rejects: u64

Rejects this router queued.

solicitations: u64

Who-Is-Router searches for unknown networks queued.

write_failures: u64

Outputs that couldn’t be written: longer than the scratch, or with a field no NPDU may carry, such as an SNET of 0.

egress_too_long: u64

Sends left out because their egress port can’t carry them: by the router’s own check (R1), or refused by the port as too long.

refused: u64

Sends the caller reported refused.

undrained: u64

Actions dropped because a call came before they were polled.
