Struct NotificationClass 

pub struct NotificationClass {
    pub notification_class: u32,
    pub priority: [u8; 3],
    pub ack_required: EventTransitionBits,
    /* private fields */
}

BACnet NotificationClass object.

Stores notification routing configuration: which priorities, acknowledgement requirements, and recipient destinations apply to event notifications referencing this class number.

Fields

notification_class: u32

The notification class number.

priority: [u8; 3]

Priority: [TO_OFFNORMAL, TO_FAULT, TO_NORMAL]. Default [255, 255, 255].

ack_required: EventTransitionBits

Transitions whose notifications require acknowledgment. Default empty.

Implementations

impl NotificationClass

pub fn with_persistence( instance: u32, name: impl Into<String>, persistence: Arc<dyn NotificationClassPersistence>, ) -> Result<Self, Error>

A Notification Class that keeps a written Recipient_List in persistence, starting from the list saved there for this object, if any. Its Notification_Class number defaults to the instance number, as with new.

Fails when the saved list cannot be loaded, or holds what a write would refuse: more than MAX_RECIPIENT_LIST_DESTINATIONS destinations, or an address recipient whose MAC is too long.

pub fn recipient_list_saved(&self) -> bool

Whether storage holds a Recipient_List a write set, now or before a restart. add_destination then leaves the list alone. Always false without persistence.

pub fn wait_for_saves(&self)

Block until the saves queued so far have run. Dropping the class waits for them too.

impl NotificationClass

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

Create a new NotificationClass object. Its Recipient_List is kept in memory only; see with_persistence.

The notification_class number defaults to the instance number.

pub fn set_description(&mut self, desc: impl Into<String>)

Set the description string.

pub fn add_destination(&mut self, dest: BACnetDestination) -> Result<(), Error>

Add a destination to the recipient list.

Refuses, as a network write would, an address recipient whose MAC is longer than BACnetAddress::MAX_MAC_LEN octets (PROPERTY / INVALID_DATA_TYPE, #1124) and a destination past the MAX_RECIPIENT_LIST_DESTINATIONS cap (RESOURCES / NO_SPACE_TO_WRITE_PROPERTY).

This configures the list the application starts with; it is not saved. On a class with_persistence whose storage holds a written Recipient_List (recipient_list_saved), the saved list wins: the destination is checked but not added.

pub fn recipient_list(&self) -> &[BACnetDestination]

The Recipient_List destinations, in list order.

Trait Implementations

impl BACnetObject for NotificationClass

fn object_identifier(&self) -> ObjectIdentifier

The object’s identifier (type + instance).

fn object_name(&self) -> &str

The object’s name.

fn read_property( &self, property: PropertyIdentifier, array_index: Option<u32>, ) -> Result<PropertyValue, Error>

Read a property value.

fn write_property( &mut self, property: PropertyIdentifier, array_index: Option<u32>, value: PropertyValue, _priority: Option<u8>, ) -> Result<(), Error>

Write a property value.

fn property_metadata(&self) -> Cow<'_, [PropertyMetadata]>

Return canonical metadata for this object’s effective property rows.

fn property_list(&self) -> Cow<'static, [PropertyIdentifier]>

List all properties this object supports in the legacy projection.

fn write_property_from( &mut self, property: PropertyIdentifier, array_index: Option<u32>, value: PropertyValue, priority: Option<u8>, _origin: &CommandOrigin, ) -> Result<(), Error>

Write with explicit actual command provenance. Standalone callers assert the origin; server boundaries additionally validate ingress or membership. Decorators must forward this hook without discarding the origin. The default preserves custom/unaffected object behavior. First-party source-tracked commands require this hook and deny context-free writing.

fn is_writable_property(&self, property: PropertyIdentifier) -> bool

Whether a property write route can accept property for this object.

fn is_array_property(&self, property: PropertyIdentifier) -> bool

Whether property accepts an array index on this object.

fn is_list_property(&self, property: PropertyIdentifier) -> bool

Whether property is a BACnetLIST on this object.

fn is_createable(&self) -> bool

Whether this object type can be created at runtime via CreateObject.

fn creation_only_properties(&self) -> &'static [PropertyIdentifier]

The properties whose whole value a CreateObject initial value may set on this object although WriteProperty can’t change it afterwards.

fn initialize_property( &mut self, _property: PropertyIdentifier, _value: PropertyValue, ) -> Result<(), Error>

Apply a CreateObject initial value to one of Self::creation_only_properties, written whole.

fn is_deleteable(&self) -> bool

Whether this object type can be deleted at runtime via DeleteObject.

fn required_properties(&self) -> Cow<'static, [PropertyIdentifier]>

List the REQUIRED properties for this object type.

fn supports_cov(&self) -> bool

Whether this object type supports COV notifications.

fn supports_subscribe_cov_property(&self) -> bool

Whether SubscribeCOVProperty and SubscribeCOVPropertyMultiple may monitor this object’s properties.

fn supports_cov_property(&self, property: PropertyIdentifier) -> bool

Whether a readable property supports property-specific COV.

fn cov_increment(&self) -> Option<f64>

COV increment for this object (objects with a COV_Increment property).

fn cov_reported_properties(&self) -> &'static [CovReportedProperty]

Properties a whole-object (SubscribeCOV) notification reports after its leading value and Status_Flags, in report order.

fn set_overridden(&mut self, _overridden: bool)

Set the OVERRIDDEN bit in StatusFlags.

fn evaluate_intrinsic_reporting(&mut self) -> Option<TransitionOutcome>

Evaluate intrinsic reporting after a present_value change.

fn tick_intrinsic_reporting(&mut self) -> Option<TransitionOutcome>

Evaluate this object’s schedule at time on today (Clause 12.24.4).

fn take_owed_schedule_writes(&mut self) -> Vec<ScheduleWrite>

Take the writes this schedule owes its targets apart from its calculation, each once, in order: a NULL to every priority slot a change of List_Of_Object_Property_References or Priority_For_Writing left behind (#1088), then the Present_Value owed out of service, for a client’s write (Clause 12.24.14) or a change of those two properties.

fn complete_schedule_write( &mut self, _write: &ScheduleWrite, _outcomes: &[ScheduleTargetOutcome], ) -> bool

Report how each target took write, one of this schedule’s writes: outcomes holds one entry per member of write.references, in order.

fn retry_refusals_naming( &self, _target: ObjectIdentifier, ) -> Option<ScheduleWrite>

The retry of the current value to the references whose last write was refused and that name target, an object just added to the database (#1440), so the refusal can clear without waiting for the next pass. None when no such refusal stands, or when the pass itself would retry nothing: out of service, outside Effective_Period, or with a NULL Present_Value. Only meaningful for Schedule objects; default returns None.

fn acknowledge_alarm( &mut self, _transition_bit: EventTransitionBits, ) -> Result<(), Error>

Acknowledge an alarm transition. Sets the transition_bit flags in acked_transitions. Returns Ok(()) if the object supports event detection, Err otherwise.
