Struct opcua_types::node_id::NodeId

pub struct NodeId {
    pub namespace: UInt16,
    pub identifier: Identifier,
}

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

Fields

namespace: UInt16

The index for a namespace

identifier: Identifier

The identifier for the node in the address space

Methods

impl NodeId

fn new<T>(namespace: UInt16, value: T) -> NodeId where
    T: 'static + Into<Identifier>, 

fn new_string(namespace: UInt16, value: &str) -> NodeId

Construct a string node id

fn is_null(&self) -> bool

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

fn null() -> NodeId

Returns a null node id

fn next_numeric() -> NodeId

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

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

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

fn to_string(&self) -> String

fn is_numeric(&self) -> bool

Test if the node id is numeric

fn is_string(&self) -> bool

Test if the node id is a string

fn is_guid(&self) -> bool

Test if the node id is a guid

fn is_byte_string(&self) -> bool

Test if the node id us a byte string

Trait Implementations

impl PartialEq for NodeId

fn eq(&self, __arg_0: &NodeId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &NodeId) -> bool

This method tests for !=.

impl Eq for NodeId

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeId

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for NodeId

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Default for NodeId

fn default() -> Self

Returns the "default value" for a type.

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) -> EncodingResult<Self>

Decodes an instance from the read stream.

impl FromStr for NodeId

type Err = StatusCode

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Into<String> for NodeId

fn into(self) -> String

Performs the conversion.

impl<'a> From<(UInt16, &'a str)> for NodeId

fn from(v: (UInt16, &'a str)) -> Self

Performs the conversion.

impl<'a> Into<ExpandedNodeId> for &'a NodeId

fn into(self) -> ExpandedNodeId
