Crate opcua_nodes 

The nodes crate contains core types for generated address spaces.

This includes types for each node class, some common enums for references, core event types, and core types for node set import.

Structs

AccessLevel

Variable access level.

Base

Base node class contains the attributes that all other kinds of nodes need. Part 3, diagram B.4

BaseEventType

This corresponds to BaseEventType definition in OPC UA Part 5

DataType

A DataType is a type of node within the AddressSpace.

DataTypeBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

DefaultTypeTree

Type managing the types in an OPC-UA server. The server needs to know about all available types, to handle things like event filters, browse filtering, etc.

EventNotifier

Node event notifier.

ImportedItem

A node with associated references produced by a type implementing NodeSetImport

ImportedReference

A reference produced by a type implementing NodeSetImport. Note that the source of this reference is given by the node in the outer ImportedItem

Method

A Method is a type of node within the AddressSpace.

MethodBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

MethodEventField

A field of an event that references a method.

NamespaceMap

Utility for handling assignment of namespaces on server startup.

NodeSet2Import

NodeSetImport implementation for dynamically loading NodeSet2 files at runtime. Note that structures must be loaded with a type loader. By default the type loader for the base types is registered, but if your NodeSet2 file uses custom types you will have to add an TypeLoader using NodeSet2Import::add_type_loader.

NodeSetNamespaceMapper

Utility handling namespaces when loading node sets.

Object

An Object is a type of node within the AddressSpace.

ObjectBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

ObjectType

An ObjectType is a type of node within the AddressSpace.

ObjectTypeBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

ParsedAttributeOperand

Parsed version of the raw opcua_types::AttributeOperand

ParsedContentFilter

Parsed version of the raw ContentFilter.

ParsedContentFilterElement

Element of a parsed content filter.

ParsedEventFilter

Parsed version of the raw EventFilter.

ParsedSimpleAttributeOperand

Parsed version of the raw SimpleAttributeOperand.

Reference

Owned OPC-UA reference.

ReferenceRef

A borrowed version of an OPC-UA reference.

ReferenceType

A ReferenceType is a type of node within the AddressSpace.

ReferenceTypeBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

References

Structure for storing and accessing OPC-UA references.

TypeProperty

A single property of a type in the type tree.

TypePropertyInverseRef

Inverse reference to a type from a property.

Variable

A Variable is a type of node within the AddressSpace.

VariableBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

VariableType

A VariableType is a type of node within the AddressSpace.

VariableTypeBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

View

A View is a type of node within the AddressSpace.

ViewBuilder

A builder for constructing a node of same name. This can be used as an easy way to create a node and the references it has to another node in a simple fashion.

Enums

FromAttributesError

Error returned when creating a node from attributes.

NodeType

The NodeType enum enumerates the different OPC-UA node classes.

ParsedOperand

Parsed and validated Operand.

ReferenceDirection

Direction of a reference in the address space.

TypeTreeNode

A node in the type tree.

Traits

AttributeQueryable

Trait for something that can be queried for attribute values.

Event

Trait implemented by all events.

EventField

Trait implemented by any type that can be a field in an event.

HasNodeId

Trait for types that have a node ID.

Node

Implemented by each node type’s to provide a generic way to set or get attributes, e.g. from the Attributes service set. Internal callers could call the setter / getter on the node if they have access to them.

NodeBase

Implemented within a macro for all Node types. Functions that return a result in an Option do so because the attribute is optional and not necessarily there.

NodeInsertTarget

Something a list of nodes can be inserted into. Implemented for AddressSpace in the server crate.

NodeSetImport

Trait for a type that wraps a nodeset import. Currently this is implemeneted by the crate::xml::NodeSet2Import type with the xml feature, and by a type in the root of node set imports generated by async-opcua-codegen

TypeTree

Trait for a type tree, a structure that provides methods to inspect type relationships. This is used for getting reference sub-types, and for events.

Functions

new_node_from_attributes

Create a new node from AddNodeAttributes.

Derive Macros

Event

Derive the Event trait. This will also generate an implementation of the EventField trait.

EventField

Derive the EventField trait.
