Struct QualifiedName 

pub struct QualifiedName {
    pub namespace_index: u16,
    pub name: UAString,
}

An identifier for a error or condition that is associated with a value or an operation.

A name qualified by a namespace.

For JSON, the namespace_index is saved as “Uri” and MUST be a numeric value or it will not parse. This is is in accordance with OPC UA spec that says to save the index as a numeric according to rules cut and pasted from spec below:

Name The Name component of the QualifiedName.

Uri The NamespaceIndexcomponent of the QualifiedNameencoded as a JSON number. The Urifield is omitted if the NamespaceIndex equals 0. For the non-reversible form, the NamespaceUriassociated with the NamespaceIndexportion of the QualifiedNameis encoded as JSON string unless the NamespaceIndexis 1 or if NamespaceUriis unknown. In these cases, the NamespaceIndexis encoded as a JSON number.

Fields

namespace_index: u16

The namespace index

name: UAString

The name.

Implementations

impl QualifiedName

pub fn new<T>(namespace_index: u16, name: T) -> QualifiedName

where T: Into<UAString>,

Create a new qualified name from namespace index and name.

pub fn null() -> QualifiedName

Create a new empty QualifiedName.

pub fn is_null(&self) -> bool

Return true if this is the null QualifiedName.

pub fn parse(raw: &str, namespaces: &NamespaceMap) -> QualifiedName

Parse a QualifiedName from a string. Note that QualifiedName parsing is unsolvable. This does a best-effort. If parsing fails, we will capture the string as a name with namespace index 0.

Trait Implementations

impl BinaryDecodable for QualifiedName

fn decode<S>(stream: &mut S, ctx: &Context<'_>) -> Result<QualifiedName, Error>

where S: Read + ?Sized,

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 QualifiedName

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>(&self, stream: &mut S, ctx: &Context<'_>) -> Result<(), Error>

where S: Write + ?Sized,

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 QualifiedName

fn clone(&self) -> QualifiedName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QualifiedName

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

Formats the value using the given formatter.

impl Default for QualifiedName

fn default() -> QualifiedName

Returns the “default value” for a type.

impl Display for QualifiedName

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

Formats the value using the given formatter.

impl From<&String> for QualifiedName

fn from(value: &String) -> QualifiedName

Converts to this type from the input type.

impl<'a> From<&'a str> for QualifiedName

fn from(value: &'a str) -> QualifiedName

Converts to this type from the input type.

impl From<QualifiedName> for DataValue

fn from(v: QualifiedName) -> DataValue

Converts to this type from the input type.

impl From<String> for QualifiedName

fn from(value: String) -> QualifiedName

Converts to this type from the input type.

impl Hash for QualifiedName

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

where __H: Hasher,

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<QualifiedName>

fn into_variant(self) -> Variant

Convert self into a variant.

impl IntoVariant for QualifiedName

fn into_variant(self) -> Variant

Convert self into a variant.

impl JsonDecodable for QualifiedName

fn decode( stream: &mut JsonStreamReader<&mut dyn Read>, ctx: &Context<'_>, ) -> Result<QualifiedName, Error>

Decode Self from a JSON stream.

impl JsonEncodable for QualifiedName

fn encode( &self, stream: &mut JsonStreamWriter<&mut dyn Write>, _ctx: &Context<'_>, ) -> Result<(), Error>

Write the type to the provided JSON writer.

impl PartialEq for QualifiedName

fn eq(&self, other: &QualifiedName) -> 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 QualifiedName

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

Try to cast the given variant to this type.

impl UaNullable for QualifiedName

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 QualifiedName

fn variant_type_id() -> VariantScalarTypeId

The variant kind this type will be represented as.

impl XmlDecodable for QualifiedName

fn decode( read: &mut XmlStreamReader<&mut dyn Read>, context: &Context<'_>, ) -> Result<QualifiedName, Error>

Decode a value from an XML stream.

impl XmlEncodable for QualifiedName

fn encode( &self, writer: &mut XmlStreamWriter<&mut dyn Write>, context: &Context<'_>, ) -> Result<(), Error>

Encode a value to an XML stream.

impl XmlType for QualifiedName

const TAG: &'static str = "QualifiedName"

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 QualifiedName

impl StructuralPartialEq for QualifiedName
