Struct Error 

pub struct Error { /* private fields */ }

General OPC-UA error.

Contains context about the request this error occured as part of, if that is possible to retrieve, as well as details about the error that caused this, and a status code.

Implementations

impl Error

pub fn new( status: StatusCode, context: impl Into<Box<dyn Error + Sync + Send>>, ) -> Error

Create a new error with the specified status code and context as a dynamic error source.

pub fn decoding(context: impl Into<Box<dyn Error + Sync + Send>>) -> Error

Create a new error with status code BadDecodingError and context as a dynamic error source.

pub fn encoding(context: impl Into<Box<dyn Error + Sync + Send>>) -> Error

Create a new error with status code BadEncodingError and context as a dynamic error source.

pub fn with_context( self, request_id: Option<u32>, request_handle: Option<u32>, ) -> Error

Add request ID and request handle to this error.

pub fn with_request_id(self, id: u32) -> Error

Add request ID to this error.

pub fn with_request_handle(self, handle: u32) -> Error

Add request handle to this error.

pub fn maybe_with_request_handle(self, handle: Option<u32>) -> Error

Utility for setting request handle when it is maybe initialized.

pub fn status(&self) -> StatusCode

Get the inner status code of this error.

pub fn full_context(&self) -> Option<(u32, u32)>

Get the full context of this error, if both fields are present.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
