Enum rodbus::RequestError

pub enum RequestError {
    Io(ErrorKind),
    Exception(ExceptionCode),
    BadRequest(InvalidRequest),
    BadFrame(FrameParseError),
    BadResponse(AduParseError),
    Internal(InternalError),
    ResponseTimeout,
    NoConnection,
    Shutdown,
}

Top level error type for the client API

Variants

Io(ErrorKind)

An I/O error occurred

Exception(ExceptionCode)

A Modbus exception was returned by the server

BadRequest(InvalidRequest)

Request was not performed because it is invalid

BadFrame(FrameParseError)

Unable to parse a frame from the server

BadResponse(AduParseError)

Response ADU was invalid

Internal(InternalError)

An internal error occurred in the library itself

These errors should never happen, but are trapped here for reporting purposes in case they ever do occur

ResponseTimeout

Timeout occurred before receiving a response from the server

NoConnection

No connection could be made to the Modbus server

Shutdown

Task processing requests has been shutdown

Trait Implementations

impl Clone for RequestError

fn clone(&self) -> RequestError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RequestError

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

Formats the value using the given formatter.

impl Display for RequestError

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

Formats the value using the given formatter.

impl Error for RequestError

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<AduParseError> for RequestError

fn from(err: AduParseError) -> Self

Converts to this type from the input type.

impl From<Error> for RequestError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ExceptionCode> for RequestError

fn from(err: ExceptionCode) -> Self

Converts to this type from the input type.

impl From<FrameParseError> for RequestError

fn from(err: FrameParseError) -> Self

Converts to this type from the input type.

impl From<InternalError> for RequestError

fn from(err: InternalError) -> Self

Converts to this type from the input type.

impl From<InvalidRange> for RequestError

fn from(x: InvalidRange) -> Self

Converts to this type from the input type.

impl From<InvalidRequest> for RequestError

fn from(err: InvalidRequest) -> Self

Converts to this type from the input type.

impl From<ReadError> for RequestError

fn from(_: ReadError) -> Self

Converts to this type from the input type.

impl From<RecvError> for RequestError

fn from(_: RecvError) -> Self

Converts to this type from the input type.

impl<T> From<SendError<T>> for RequestError

fn from(_: SendError<T>) -> Self

impl PartialEq<RequestError> for RequestError

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

This method tests for self and other values to be equal, and is used by ==.

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

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