Errors that can occur while executing a master task

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooManyRequests

There are too many user requests queued

Link(LinkError)

An error occurred at the link level

Transport

An error occurred at the transport/app level

RejectedByIin2(Iin)

Outstation returned IIN.2 bit(s) indicating failure

MalformedResponse(ObjectParseError)

A response to the task’s request was malformed

UnexpectedResponseHeaders

The response contains unexpected or invalid headers or data that don’t match the request

NonFinWithoutCon

Non-final response not requesting confirmation

NeverReceivedFir

Received a non-FIR response when expecting the FIR bit

UnexpectedFir

Received FIR bit after already receiving FIR

MultiFragmentResponse

Received a multi-fragmented response when expecting FIR/FIN

ResponseTimeout

The response timed-out

WriteError

Insufficient buffer space to serialize the request or data can’t be encoded

BadEncoding(BadEncoding)

Request data could not be encoded

NoSuchAssociation(EndpointAddress)

The requested association does not exist (not configured)

NoConnection

There is not connection at the transport level

Shutdown

The master was disabled or shutdown

Disabled

The master was disabled

Trait Implementations

impl Clone for TaskError

fn clone(&self) -> TaskError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskError

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

Formats the value using the given formatter.

impl Display for TaskError

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

Formats the value using the given formatter.

impl Error for TaskError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<FileError> for TaskError

fn from(err: FileError) -> Self

Converts to this type from the input type.

impl From<ObjectParseError> for TaskError

fn from(err: ObjectParseError) -> Self

Converts to this type from the input type.

impl From<RecvError> for TaskError

fn from(_: RecvError) -> Self

Converts to this type from the input type.

impl From<Shutdown> for TaskError

fn from(_: Shutdown) -> Self

Converts to this type from the input type.

impl From<TaskError> for CommandError

fn from(err: TaskError) -> Self

Converts to this type from the input type.

impl From<TaskError> for FileError

fn from(err: TaskError) -> Self

Converts to this type from the input type.

impl From<TaskError> for TimeSyncError

fn from(err: TaskError) -> Self

Converts to this type from the input type.

impl From<TaskError> for WriteError

fn from(err: TaskError) -> Self

Converts to this type from the input type.

impl From<WriteError> for TaskError

fn from(_: WriteError) -> Self

Converts to this type from the input type.

impl PartialEq for TaskError

fn eq(&self, other: &TaskError) -> 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.
