Module server 

BACnetServer: builder, APDU dispatch, and lifecycle management.

The server wraps a NetworkLayer behind Arc (shared with the dispatch task), owns an ObjectDatabase via Arc<RwLock>, and spawns a dispatch task that routes incoming APDUs to service handlers.

Structs

AtomicReadFileBudget

Positive local limits, independent of peer APDU size and segmentation.

AtomicWriteFileBudget

Positive payload limits independent of peer APDU size and segmentation.

AuditReportersConfig

A bounded set of target READ/WRITE/CREATE/DELETE Reporters sharing one Device recipient.

BACnetServer

BACnet server with APDU dispatch and service handling.

BipServerBuilder

BIP-specific builder that constructs BipTransport from interface/port/broadcast fields.

ClockConfig

Validated civil-time settings for the bundled server clock.

DccDisableRateLimit

Optional global authorization budget for DISABLE_INITIATION, not ingress protection. Use Some(Default::default()) to enable; server configuration defaults to None.

DccOutcomeCounters

Lifetime totals for completed, admitted DCC handlers, saturating at u64::MAX. New servers start at zero. Fields are independently sampled, not an atomic aggregate. These are local operational telemetry, not a durable audit log.

DccSourceRestriction

Validated static exact-source restriction. An empty list denies every source.

DeviceBinding

One explicitly configured unicast route to a Device object.

DiscoveryCounters

Operational counters for discovery requests and responses.

DiscoveryPolicy

Configuration policy for discovery rate limiting and duplicate suppression.

EventNotificationCounters

Lifetime totals of event notifications that were not delivered, each saturating at u64::MAX. A new server starts at zero, and the totals stay readable after stop(). Fields are sampled independently, not as one atomic aggregate. Each refusal also logs a warning (the forwarding cap’s at most once a minute); these totals are the running signal, not an audit log.

GetAlarmSummaryBudget

Positive local limits for a complete GetAlarmSummary response.

GetEnrollmentSummaryBudget

Positive limits on total database objects and complete logical ACK bytes.

GetEventInformationBudget

Positive local limits; callback allocations, CPU and RSS are not bounded. Every remaining object’s strict projection is validated on admitted requests.

IAmBroadcaster

Cloneable handle for unsolicited I-Am announcements while its server runs.

LocalAuthorizationResult

Complete evaluation and the event records installed by one local attempt.

ReadPropertyMultipleBudget

Local ReadPropertyMultiple planning and encoded service-ACK limits.

ReadRangeBudget

Positive limits on returned items and the complete logical service ACK. APDU/NPDU envelopes are excluded. Unsegmented peers may further reduce bytes. Full property reads, identity retrieval/selection, and one trial item encoding remain outside these limits.

ReinitializeContext

The ReinitializeDevice request a ReinitializeHandler is asked to carry out, and who sent it.

RequestAdmissionCounters

Independently sampled counters for one server lifetime, not an atomic aggregate. Admitted totals count registrations, not successful responses. Active counts include registered futures not yet polled and exclude completed unreaped tasks.

RequestAdmissionPolicy

Global and logical-peer top-level handler limits with a strict recovery reserve. Defaults are provisional owner policy, not benchmark-derived values.

ScServerBuildersc-tls

SC-specific server builder.

ServerBuilder

Generic builder for BACnetServer with a pre-built transport. The transport type defaults to AnyTransport, as BACnetServer’s does.

ServerConfig

Server configuration.

TimeSyncData

Data from a TimeSynchronization request.

TimeSyncPolicy

Default-allow inbound TimeSynchronization / UTCTimeSynchronization policy.

TimeSyncRateLimit

Opt-in token bucket for accepted local and UTC time-sync requests combined.

TimeSyncSourceRestriction

Validated exact-source allowlist. A configured empty list denies everyone. None in TimeSyncPolicy leaves sources unrestricted.

Enums

CovAckResult

Result of a confirmed request from the receiving device’s side.

DccPolicy

Local DeviceCommunicationControl authorization, not source authentication.

DccSource

Exact claimed DCC source, not an authenticated principal (including SC VMAC).

DccState

The communication state DeviceCommunicationControl has put the server in (Clause 16.1).

TimeSyncSource

Exact claimed time-sync source, not an authenticated principal.

Constants

MAX_FORWARDED_DESTINATIONS

The most destinations one notification is forwarded to, across every Notification Forwarder in this device that takes it: as many as one forwarder’s full Recipient_List and Subscribed_Recipients name, so no single forwarder is cut short. It bounds how far one received notification can multiply. Only copies that would be sent count: a destination the loop rules refuse, whose route is skipped, or whose copy is too large is not. Destinations naming this device’s own Device object, which hand the notification on within the device, do not count either. The destinations past the cap count in EventNotificationCounters::forwarding_cap_dropped.

RECEIVED_EVENT_LOG_RATE

The records one source may add to the Event Logs that collect received notifications in each one-second window.

RECEIVED_EVENT_LOG_SOURCES

The sources that hold an allowance of their own at a time; any other source shares one more.

Functions

drop_database_off_runtime

Let go of a handle on an object database without parking an async runtime’s worker thread (#1513).

Type Aliases

ReinitializeHandler

Carries out a ReinitializeDevice request (Clause 16.4) on a full server or an endpoint session.
