Struct RemoteAlarm 

pub struct RemoteAlarm {
    pub severity: i32,
    pub status: i32,
    pub message: String,
}

Ungated remote alarm snapshot for a link — the remote (severity, status, message) the upstream PV carried at the last successful value read, WITHOUT the maximize-severity (MS/NMS/MSI) gate that LinkSet::alarm_severity applies for owning-record propagation.

This is the DB-link inspection counterpart pvxs exposes through dbGetAlarm / dbGetAlarmMsg — pvaGetAlarmMsg returns the cached snap_severity / snap_message directly and never consults the link’s sevr mode (pvxs/ioc/pvalink_lset.cpp:542-575). A default NMS link must still report its remote severity here even though it does not maximize the owning record’s severity.

Fields

severity: i32

Remote alarm severity (0 = NO_ALARM … 3 = INVALID), the raw cached alarm.severity — never gated by the link’s sevr mode.

status: i32

Remote alarm status code, derived from severity exactly as pvxs pvaGetAlarmMsg does (LINK_ALARM when severity is non-NO_ALARM, else NO_ALARM — pvalink_lset.cpp:551). See RemoteAlarm::from_severity_message.

message: String

Remote alarm.message. Empty when the remote carried none or the severity is NO_ALARM (pvxs clears snap_message unless snap_severity != 0 — pvalink_lset.cpp:418-422).

Implementations

impl RemoteAlarm

pub fn from_severity_message(severity: i32, message: String) -> Self

Build a snapshot whose status is derived from severity exactly as pvxs pvaGetAlarmMsg (pvalink_lset.cpp:551): LINK_ALARM when the remote severity is non-NO_ALARM, else NO_ALARM. status and severity cannot disagree by construction.
