Struct AlertEnrollmentObject 

pub struct AlertEnrollmentObject {
    pub present_value: ObjectIdentifier,
    pub event_detection_enable: bool,
    pub event_enable: u8,
    pub notification_class: u32,
    /* private fields */
}

BACnet AlertEnrollment object (type 52).

Provides the Alert Enrollment property surface from ASHRAE 135-2020 Table 12-61. Present_Value identifies the object that last provided an alert; recording that source does not itself evaluate or generate an event.

Fields

present_value: ObjectIdentifier

Object that last provided an alert.

event_detection_enable: bool

Whether event detection is enabled.

Prefer Self::set_event_detection_enable so disabling also clears stored event state. This field remains public for compatibility; property reads and internal transition hooks still enforce the disabled-state invariant after a direct assignment. Re-enable through the setter as well: a direct FALSE-to-TRUE assignment cannot run the reset and may expose state stored before the direct disable.

event_enable: u8

Event enable bits: 3-bit (TO_OFFNORMAL, TO_FAULT, TO_NORMAL).

notification_class: u32

Notification class number.

Implementations

impl AlertEnrollmentObject

pub fn new( instance: u32, name: impl Into<String>, initial_source: ObjectIdentifier, ) -> Result<Self, Error>

Create a new AlertEnrollment object with the object that most recently provided an alert.

pub fn record_alert_source(&mut self, source: ObjectIdentifier)

Record the object that most recently provided an alert.

This source-ownership hook updates only Present_Value; it does not evaluate an alert, change event/acknowledgement history, or generate a notification.

pub fn set_event_detection_enable(&mut self, enabled: bool)

Enable or disable event detection.

Disabling applies the Clause 13.2.2.1 initial conditions immediately.
