Implementations

impl EtherNetIpError

pub fn is_retriable(&self) -> bool

Returns true if the error is likely retriable (e.g. timeout, connection lost). Use this to decide whether to retry an operation or reconnect.

Trait Implementations

impl Debug for EtherNetIpError

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

Formats the value using the given formatter.

impl Display for EtherNetIpError

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

Formats the value using the given formatter.

impl Error for EtherNetIpError

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<Error> for EtherNetIpError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for EtherNetIpError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
