Structural action workflow failure.

Variants

ResponsePending

Another request cannot start before its response is observed.

UnexpectedObservation

A response was supplied without one admitted request.

Terminal

The workflow already reached a terminal state.

MonotonicRollback

Caller monotonic time moved backwards.

TimeOverflow

Monotonic timestamp arithmetic overflowed.

ObservationLimitExceeded

The unconditional observation limit was reached while still running.

InvalidProgress

Provider progress exceeded 100.

ProgressRegressed

Provider progress regressed without an explicit reset.

ProgressResetForbidden

Provider progress reset was not admitted.

ProgressResetLimitExceeded

Provider progress exhausted its reset budget.

ZeroDelay

Backoff requested a zero delay.

DelayLimitExceeded

Backoff requested more than the per-delay bound.

CumulativeDelayExceeded

Backoff exhausted the cumulative delay budget.

ElapsedBudgetExceeded

Backoff would reach or exceed the elapsed budget.

impl Eq for ActionPollError

impl Error for ActionPollError

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.
