Fields

elements: Option<Vec<RelativePathElement>>

Implementations

impl RelativePath

pub fn from_str<CB>( path: &str, node_resolver: &CB, ) -> Result<RelativePath, RelativePathError>

where CB: Fn(u16, &str) -> Option<NodeId>,

Converts a string into a relative path. Caller must supply a node_resolver which will be used to look up nodes from their browse name. The function will reject strings that look unusually long or contain too many elements.

Trait Implementations

impl BinaryDecodable for RelativePath

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 RelativePath

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 RelativePath

fn clone(&self) -> RelativePath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelativePath

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

Formats the value using the given formatter.

impl Default for RelativePath

fn default() -> RelativePath

Returns the “default value” for a type.

impl From<&[QualifiedName]> for RelativePath

fn from(value: &[QualifiedName]) -> Self

Converts to this type from the input type.

impl<'a> From<&'a RelativePath> for String

fn from(path: &'a RelativePath) -> String

Converts to this type from the input type.

impl JsonDecodable for RelativePath

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

Decode Self from a JSON stream.

impl JsonEncodable for RelativePath

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

Write the type to the provided JSON writer.

impl MessageInfo for RelativePath

fn type_id(&self) -> ObjectId

The binary type id associated with the message

fn json_type_id(&self) -> ObjectId

The JSON type id associated with the message.

fn xml_type_id(&self) -> ObjectId

The XML type id associated with the message.

fn data_type_id(&self) -> DataTypeId

The data type id associated with the message.

impl PartialEq for RelativePath

fn eq(&self, other: &RelativePath) -> 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 TryFrom<&String> for RelativePath

type Error = RelativePathError

The type returned in the event of a conversion error.

fn try_from(value: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for RelativePath

type Error = RelativePathError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for RelativePath

type Error = RelativePathError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.

impl UaNullable for RelativePath

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 XmlDecodable for RelativePath

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

Decode a value from an XML stream.

impl XmlEncodable for RelativePath

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

Encode a value to an XML stream.

impl XmlType for RelativePath

const TAG: &'static str = "RelativePath"

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.
