Struct DataType 

pub struct DataType { /* private fields */ }

A DataType is a type of node within the AddressSpace.

Implementations

impl DataType

pub fn new( node_id: &NodeId, browse_name: impl Into<QualifiedName>, display_name: impl Into<LocalizedText>, is_abstract: bool, ) -> DataType

Create a new data type.

pub fn new_full( base: Base, is_abstract: bool, data_type_definition: Option<DataTypeDefinition>, ) -> Self

Create a new data type with all attributes, may change if new attributes are added to the OPC-UA standard.

pub fn from_attributes( node_id: &NodeId, browse_name: impl Into<QualifiedName>, attributes: DataTypeAttributes, ) -> Result<Self, FromAttributesError>

Create a new data type from DataTypeAttributes.

pub fn is_valid(&self) -> bool

Get whether this data type is valid.

pub fn is_abstract(&self) -> bool

Get the IsAbstract attribute for this data type.

pub fn set_is_abstract(&mut self, is_abstract: bool)

Set the IsAbstract attribute for this data type.

pub fn set_data_type_definition( &mut self, data_type_definition: Option<DataTypeDefinition>, )

Set the data type definition of this data type.

pub fn data_type_definition(&self) -> Option<&DataTypeDefinition>

Get the data type definition of this data type.

Trait Implementations

impl Debug for DataType

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

Formats the value using the given formatter.

impl Default for DataType

fn default() -> Self

Returns the “default value” for a type.

impl From<DataType> for NodeType

fn from(value: DataType) -> Self

Converts to this type from the input type.

impl Node for DataType

fn get_attribute_max_age( &self, timestamps_to_return: TimestampsToReturn, attribute_id: AttributeId, index_range: &NumericRange, data_encoding: &DataEncoding, max_age: f64, ) -> Option<DataValue>

Finds the attribute and value. The param max_age is a hint in milliseconds:

fn set_attribute( &mut self, attribute_id: AttributeId, value: Variant, ) -> Result<(), StatusCode>

Sets the attribute with the new value

fn get_attribute( &self, timestamps_to_return: TimestampsToReturn, attribute_id: AttributeId, index_range: &NumericRange, data_encoding: &DataEncoding, ) -> Option<DataValue>

Finds the attribute and value.

impl NodeBase for DataType

fn node_class(&self) -> NodeClass

Returns the node class - Object, ObjectType, Method, DataType, ReferenceType, Variable, VariableType or View

fn node_id(&self) -> &NodeId

fn set_display_name(&mut self, display_name: LocalizedText)

Sets the node’s display name

fn description(&self) -> Option<&LocalizedText>

Get the description of this node.

fn set_description(&mut self, description: LocalizedText)

Set the description of this node.

fn write_mask(&self) -> Option<WriteMask>

Get the write mask of this node.

fn set_write_mask(&mut self, write_mask: WriteMask)

Set the write mask of this node.

fn user_write_mask(&self) -> Option<WriteMask>
