Struct VariableType 

pub struct VariableType { /* private fields */ }

A VariableType is a type of node within the AddressSpace.

Implementations

impl VariableType

pub fn new( node_id: &NodeId, browse_name: impl Into<QualifiedName>, display_name: impl Into<LocalizedText>, data_type: NodeId, is_abstract: bool, value_rank: i32, ) -> VariableType

pub fn new_full( base: Base, data_type: NodeId, is_abstract: bool, value_rank: i32, value: Option<DataValue>, array_dimensions: Option<Vec<u32>>, ) -> Self

Create a new variable 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: VariableTypeAttributes, ) -> Result<Self, FromAttributesError>

Create a new variable type from VariableTypeAttributes.

pub fn is_valid(&self) -> bool

Get whether this type is valid.

pub fn data_type(&self) -> &NodeId

Get the data type of this variable type.

pub fn set_data_type(&mut self, data_type: impl Into<NodeId>)

Set the data type of this variable type.

pub fn is_abstract(&self) -> bool

Get the IsAbstract attribute for this variable type.

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

Set the IsAbstract attribute for this variable type.

pub fn value_rank(&self) -> i32

Get the value rank of this variable type.

pub fn set_value_rank(&mut self, value_rank: i32)

Set the value rank of this variable type.

pub fn array_dimensions(&self) -> Option<Vec<u32>>

Get the array dimensions of this type.

pub fn set_array_dimensions(&mut self, array_dimensions: &[u32])

Set the array dimensions of this type.

pub fn value(&self) -> Option<&DataValue>

Get the default value for instances of this type.

pub fn set_value(&mut self, value: impl Into<Variant>)

Set the default value for instances of this type.

pub fn set_data_value(&mut self, value: DataValue)

Set the default value for instances of this type to a full data value.

Trait Implementations

impl Debug for VariableType

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

Formats the value using the given formatter.

impl Default for VariableType

fn default() -> Self

Returns the “default value” for a type.

impl From<VariableType> for NodeType

fn from(value: VariableType) -> Self

Converts to this type from the input type.

impl Node for VariableType

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.
