Implementations

impl ClientError

pub fn command(&self) -> Option<String>

Returns the command(s) string suitable for passing into a Response

pub fn was_due_to_message(&self) -> bool

If the error contents were likely caused by something about the mostly recently attempted message, rather than a transport issue, or a carry-over from a prior message (eg: previous message was rejected and destination chose to drop the connection, which we detect later in RSET on the next message), then we return true. The expectation is that the caller will transiently fail the message for later retry. If we return false then the caller might decide to try that same message again more immediately on a separate connection

Trait Implementations

impl Clone for ClientError

fn clone(&self) -> ClientError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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<ErrorStack> for ClientError

fn from(source: ErrorStack) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for ClientError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
