Struct EventLogObject 

pub struct EventLogObject { /* private fields */ }

BACnet EventLog object.

Ring buffer of timestamped event log records. The application calls add_record() to log event data. Uses the same BACnetLogRecord encoding as TrendLog.

Implementations

impl EventLogObject

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

Create a new EventLog object.

pub fn add_record(&mut self, record: BACnetLogRecord)

Add a BACnetLogRecord to the event log buffer.

pub fn records(&self) -> &VecDeque<BACnetLogRecord>

Get the current buffer contents.

pub fn clear(&mut self)

Clear the buffer.

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

Set the description string.

Trait Implementations

impl BACnetObject for EventLogObject

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

List all properties this object supports.

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

List the REQUIRED properties for this object type.

fn cov_increment(&self) -> Option<f32>

COV increment for this object (analog objects only).

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

Evaluate intrinsic reporting after a present_value change.

fn tick_schedule( &mut self, _day_of_week: u8, _hour: u8, _minute: u8, ) -> Option<(PropertyValue, Vec<(ObjectIdentifier, u32)>)>

Evaluate this object’s schedule for the given time (Clause 12.24).

fn acknowledge_alarm(&mut self, _transition_bit: u8) -> Result<(), Error>

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

fn add_trend_record(&mut self, _record: BACnetLogRecord)

Add a trend log record (only meaningful for TrendLog / TrendLogMultiple).
