Struct opcua_types::node_id::NodeId

pub struct NodeId {
    pub namespace: u16,
    pub identifier: Identifier,
}

An identifier for a node in the address space of an OPC UA Server.

Fields

namespace: u16

The index for a namespace

identifier: Identifier

The identifier for the node in the address space

Methods

impl NodeId

pub fn new<T>(namespace: u16, value: T) -> NodeId where
    T: 'static + Into<Identifier>, 

pub fn is_null(&self) -> bool

Test if the node id is null, i.e. 0 namespace and 0 identifier

pub fn null() -> NodeId

Returns a null node id

pub fn next_numeric() -> NodeId

pub fn as_object_id(&self) -> Result<ObjectId, ()>

Extracts an ObjectId from a node id, providing the node id holds an object id

pub fn as_reference_type_id(&self) -> Result<ReferenceTypeId, ()>

pub fn is_numeric(&self) -> bool

Test if the node id is numeric

pub fn is_string(&self) -> bool

Test if the node id is a string

pub fn is_guid(&self) -> bool

Test if the node id is a guid

pub fn is_byte_string(&self) -> bool

Test if the node id us a byte string

Trait Implementations

impl BinaryEncoder<NodeId> for NodeId

fn byte_len(&self) -> usize

Returns the byte length of the structure. This calculation should be exact and as efficient as possible.

fn encode<S: Write>(&self, stream: &mut S) -> EncodingResult<usize>

Encodes the instance to the write stream.

fn decode<S: Read>(
    stream: &mut S,
    decoding_limits: &DecodingLimits
) -> EncodingResult<Self>

Decodes an instance from the read stream. The decoding limits are restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.
