Error returned by SdoClient methods

Variants

NoResponse

Timeout while awaiting an expected response

MalformedResponse

Received a response that could not be interpreted

UnexpectedResponse

Received a valid SdoResponse, but with an unexpected command specifier

Fields

expecting: String

The type of response which was expected

response: SdoResponse

The response which was received

ServerAbort

Received a ServerAbort response from the node

Fields

index: u16

Index of the SDO access which was aborted

sub: u8

Sub index of the SDO access which was aborted

abort_code: RawAbortCode

Reason for the abort

ToggleNotAlternated

Received a response with the wrong toggle bit

MismatchedObjectIndex

Received a response with a different index/sub value than was requested

Fields

expected: (u16, u8)

The object ID which was expected to be echoed back

received: (u16, u8)

The received object ID

UnexpectedSize

An SDO upload response had a size that did not match the expected size

SocketSendFailed

Failed to write a message to the socket

Fields

message: String

A string describing the error reason

BlockSizeChangedTooSmall

An SDO server shrunk the block size while requesting retransmission

Hopefully no node will ever do this, but it’s a possible corner case, since servers are allowed to change the block size between each block, and can request resend of part of a block by not acknowledging all segments.

CrcMismatch

The CRC on a block upload did not match

Trait Implementations

impl Clone for SdoClientError

fn clone(&self) -> SdoClientError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SdoClientError

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

Formats the value using the given formatter.

impl Display for SdoClientError

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

Formats the value using the given formatter.

impl Error for SdoClientError

where Self: Debug + Display,

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

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

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 ErrorCompat for SdoClientError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl PartialEq for SdoClientError

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