Struct ExpandedNodeId 

pub struct ExpandedNodeId {
    pub node_id: NodeId,
    pub namespace_uri: UAString,
    pub server_index: u32,
}

A NodeId that allows the namespace URI to be specified instead of an index.

Fields

node_id: NodeId

The inner NodeId.

namespace_uri: UAString

The full namespace URI. If this is set, the node ID namespace index may be zero.

server_index: u32

The server index. 0 means current server.

Implementations

impl ExpandedNodeId

pub fn new<T>(value: T) -> ExpandedNodeId

where T: 'static + Into<ExpandedNodeId>,

Creates an expanded node id from a node id

pub fn new_with_namespace( namespace: &str, value: impl Into<Identifier> + 'static, ) -> Self

Creates an expanded node id from a namespace URI and an identifier.

pub fn null() -> ExpandedNodeId

Return a null ExpandedNodeId.

pub fn is_null(&self) -> bool

Return true if this expanded node ID is null.

pub fn try_resolve<'a>( &'a self, namespaces: &NamespaceMap, ) -> Option<Cow<'a, NodeId>>

Try to resolve the expanded node ID into a NodeId. This will directly return the inner NodeId if namespace URI is null, otherwise it will try to return a NodeId with the namespace index given by the namespace uri. If server index is non-zero, this will always return None, otherwise, it will return None if the namespace is not in the namespace map.

Trait Implementations

impl BinaryDecodable for ExpandedNodeId

fn decode<S: Read + ?Sized>( stream: &mut S, ctx: &Context<'_>, ) -> EncodingResult<Self>

Decodes an instance from the read stream. The decoding options contains 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.

impl BinaryEncodable for ExpandedNodeId

fn byte_len(&self, ctx: &Context<'_>) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

fn encode<S: Write + ?Sized>( &self, stream: &mut S, ctx: &Context<'_>, ) -> EncodingResult<()>

Encodes the instance to the write stream.

fn override_encoding(&self) -> Option<BuiltInDataEncoding>

Override the extension object encoding used for this type. This only makes sense if the type can only ever be encoded using a single built-in encoding.

fn encode_to_vec(&self, ctx: &Context<'_>) -> Vec<u8>

Convenience method for encoding a message straight into an array of bytes. It is preferable to reuse buffers than to call this so it should be reserved for tests and trivial code.

impl Clone for ExpandedNodeId

fn clone(&self) -> ExpandedNodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpandedNodeId

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

Formats the value using the given formatter.

fn default() -> ExpandedNodeId

Returns the “default value” for a type.

impl Display for ExpandedNodeId

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

Formats the value using the given formatter.

Converts to this type from the input type.

impl From<NodeId> for ExpandedNodeId

fn from(v: NodeId) -> Self

Converts to this type from the input type.

impl From<ObjectId> for ExpandedNodeId

fn from(r: ObjectId) -> Self

Converts to this type from the input type.

impl From<ObjectTypeId> for ExpandedNodeId

fn from(r: ObjectTypeId) -> Self

Converts to this type from the input type.

impl From<ReferenceTypeId> for ExpandedNodeId

fn from(r: ReferenceTypeId) -> Self

Converts to this type from the input type.

impl From<VariableId> for ExpandedNodeId

fn from(r: VariableId) -> Self

Converts to this type from the input type.

impl From<VariableTypeId> for ExpandedNodeId

fn from(r: VariableTypeId) -> Self

Converts to this type from the input type.

impl FromStr for ExpandedNodeId

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 Hash for ExpandedNodeId

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoVariant for Box<ExpandedNodeId>

fn into_variant(self) -> Variant

Convert self into a variant.

impl IntoVariant for ExpandedNodeId

fn into_variant(self) -> Variant

Convert self into a variant.

impl JsonDecodable for ExpandedNodeId

fn decode( stream: &mut JsonStreamReader<&mut dyn Read>, _ctx: &Context<'_>, ) -> EncodingResult<Self>

Decode Self from a JSON stream.

impl JsonEncodable for ExpandedNodeId

fn encode( &self, stream: &mut JsonStreamWriter<&mut dyn Write>, ctx: &Context<'_>, ) -> EncodingResult<()>

Write the type to the provided JSON writer.

impl PartialEq for ExpandedNodeId

fn eq(&self, other: &ExpandedNodeId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFromVariant for ExpandedNodeId

fn try_from_variant(v: Variant) -> Result<Self, Error>

Try to cast the given variant to this type.

impl UaNullable for ExpandedNodeId

fn is_ua_null(&self) -> bool

Return true if this value is null, meaning it can be left out when being encoded in JSON and XML encodings.

impl VariantType for ExpandedNodeId

impl XmlType for ExpandedNodeId

const TAG: &'static str = "ExpandedNodeId"

The static fallback tag for this type. Convenience feature, but also used in nested types.

fn tag(&self) -> &str

The XML tag name for this type.

impl Eq for ExpandedNodeId
