Enum HandoffAckError 

pub enum HandoffAckError {
    TokenNotPending,
    AckDeadlineExceeded {
        backend: PendingHandoffBackend,
        deadline: Duration,
    },
}

Errors raised when a backend acknowledgement cannot complete a handoff.

Variants

TokenNotPending

The token is unknown, already acknowledged, or already expired.

AckDeadlineExceeded

The acknowledgement arrived after the broker ACK deadline.

Fields

backend: PendingHandoffBackend

Backend that acknowledged too late.

deadline: Duration

Deadline that was exceeded.

Implementations

impl HandoffAckError

pub fn attempt_failure(&self) -> Option<HandoffAttemptFailure>

Map this error onto the shared handoff failure classification, when it represents a backend ACK timeout.

Trait Implementations

impl Clone for HandoffAckError

fn clone(&self) -> HandoffAckError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandoffAckError

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

Formats the value using the given formatter.

impl Display for HandoffAckError

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

Formats the value using the given formatter.

impl Eq for HandoffAckError

impl Error for HandoffAckError

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 PartialEq for HandoffAckError

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