Enum CompletionWaitError 

pub enum CompletionWaitError {
    ChannelClosed,
    AttachmentReplaced,
    AuthorityUnavailable(String),
}

Mechanical failure while waiting for completion plumbing.

This is intentionally separate from CompletionOutcome: a closed waiter channel or missing generated completion authority is not a public runtime result class.

Variants

ChannelClosed

AttachmentReplaced

The exact executor attachment that admitted this request was replaced before its waiter resolved. The old input is durably cancelled; a retry is a new request owned by the successor attachment. Replacement execution must never be reported as the old request’s success.

AuthorityUnavailable(String)

Implementations

impl CompletionWaitError

pub fn wait_failure_observation( &self, ) -> RuntimeCompletionWaitFailureObservation

pub const fn is_attachment_replaced(&self) -> bool

Stable typed predicate for retryable attachment replacement. Surfaces must not infer this class from an error string.

Trait Implementations

impl Clone for CompletionWaitError

fn clone(&self) -> CompletionWaitError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompletionWaitError

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

Formats the value using the given formatter.

impl Display for CompletionWaitError

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

Formats the value using the given formatter.

impl Eq for CompletionWaitError

impl Error for CompletionWaitError

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 CompletionWaitError

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

Equality operator ==.

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

Inequality operator !=.
