Struct BaseEventType 

pub struct BaseEventType {

    pub event_id: ByteString,
    pub event_type: NodeId,
    pub source_node: NodeId,
    pub source_name: UAString,
    pub time: DateTime,
    pub receive_time: DateTime,
    pub local_time: Option<TimeZoneDataType>,
    pub message: LocalizedText,
    pub severity: u16,
    pub condition_class_id: Option<NodeId>,
    pub condition_class_name: Option<LocalizedText>,
    pub condition_sub_class_id: Option<Vec<NodeId>>,
    pub condition_sub_class_name: Option<Vec<LocalizedText>>,
}

This corresponds to BaseEventType definition in OPC UA Part 5

Fields

event_id: ByteString

A unique identifier for an event, e.g. a GUID in a byte string

event_type: NodeId

Event type describes the type of event

source_node: NodeId

Source node identifies the node that the event originated from or null.

source_name: UAString

Source name provides the description of the source of the event, e.g. the display of the event source

time: DateTime

Time provides the time the event occurred. As close to the event generator as possible.

receive_time: DateTime

Receive time provides the time the OPC UA server received the event from the underlying device of another server.

local_time: Option<TimeZoneDataType>

Local time (optional) is a structure containing the offset and daylightsaving flag.

message: LocalizedText

Message provides a human readable localizable text description of the event.

severity: u16

Severity is an indication of the urgency of the event. Values from 1 to 1000, with 1 as the lowest severity and 1000 being the highest. A value of 1000 would indicate an event of catastrophic nature.

Guidance:

• 801-1000 - High
• 601-800 - Medium High
• 401-600 - Medium
• 201-400 - Medium Low
• 1-200 - Low

condition_class_id: Option<NodeId>

Condition Class Id specifies in which domain this Event is used.

condition_class_name: Option<LocalizedText>

Condition class name specifies the name of the condition class of this event, if set.

condition_sub_class_id: Option<Vec<NodeId>>

ConditionSubClassId specifies additional classes that apply to the Event. It is the NodeId of the corresponding subtype of BaseConditionClassType.

condition_sub_class_name: Option<Vec<LocalizedText>>

Condition sub class name specifies the names of additional classes that apply to the event.

Implementations

impl BaseEventType

pub fn new_now( type_id: impl Into<NodeId>, event_id: ByteString, message: impl Into<LocalizedText>, ) -> Self

Create a new event with Time set to current time.

pub fn new( type_id: impl Into<NodeId>, event_id: ByteString, message: impl Into<LocalizedText>, time: DateTime, ) -> Self

Create a new event.

pub fn new_event( type_id: impl Into<NodeId>, event_id: ByteString, message: impl Into<LocalizedText>, _namespace: &NamespaceMap, time: DateTime, ) -> Self

Create a new event, resolving the event type ID.

pub fn set_source_node(self, source_node: NodeId) -> Self

Set the event source node.

pub fn set_source_name(self, source_name: UAString) -> Self

Set the event source name.

pub fn set_receive_time(self, receive_time: DateTime) -> Self

Set the event receive time.

pub fn set_severity(self, severity: u16) -> Self

Set the event severity.

Trait Implementations
