    pub subscriber_mac: MacAddr,
    pub subscriber_network: Option<NpduAddress>,
    pub subscriber_process_identifier: u32,
    pub monitored_object_identifier: ObjectIdentifier,

    pub notification_kind: CovNotificationKind,
    pub timestamped: bool,
}

Proposed COV subscription data. Table acceptance validates its canonical identity and returns an immutable CovSubscriptionSnapshot for delivery.

Fields

subscriber_mac: MacAddr

Immediate delivery MAC: the local subscriber or its current router.

subscriber_network: Option<NpduAddress>

Routed source address when the subscriber is behind a BACnet router.

subscriber_process_identifier: u32

Process identifier chosen by the subscriber.

monitored_object_identifier: ObjectIdentifier

The object being monitored.

issue_confirmed_notifications: bool

Notification form. Mutable renewal data for ordinary/Single subscriptions; part of the canonical identity for Multiple references.

expires_at: Option<Instant>

When this subscription expires (None = infinite lifetime), on tokio’s clock: tokio::time::Instant::now().into_std() plus the lifetime, which is Instant::now() plus it unless a test has paused the clock.

last_notified_observation: Option<CovObservation>

Last delivered bounded observation, including specialized command fields.

monitored_property: Option<PropertyIdentifier>

Monitored property for Single-property and Multiple-reference subscriptions.

monitored_property_array_index: Option<u32>

Accepted property index; absent, zero and element indexes are independent.

cov_increment: Option<f32>

COV increment override (SubscribeCOVProperty only).

notification_kind: CovNotificationKind

Notification service family used for this subscription.

timestamped: bool

Whether COVNotificationMultiple values should include timeOfChange.

Implementations

impl CovSubscription

pub fn endpoint(&self) -> SubscriberEndpoint

Current immediate transport route and original routed source.

pub fn key(&self) -> Result<CovSubscriptionKey, Error>

Validate and derive the sole table identity from this proposed subscription.

impl CovSubscription

pub fn recipient(&self) -> CovRecipient

Original client address shared by subscription identity and accounting. Process, family and monitored coordinates additionally distinguish subscriptions.

Trait Implementations

impl Clone for CovSubscription

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CovSubscription

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
