Strongly-typed error domain for scheduler operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidCron(String, String)

Invalid cron expression syntax.

RuntimeUnavailable

The scheduler was started outside an active Tokio runtime.

TaskTimedOut

A task exceeded its configured execution deadline.

Fields

label: String

Cron expression identifying the task.

timeout_ms: u64

Configured timeout in milliseconds.

TaskPanicked

A task panicked. The panic is contained in its isolated Tokio task.

Fields

label: String

Cron expression identifying the task.

TaskCancelled

A task execution was unexpectedly cancelled.

Fields

label: String

Cron expression identifying the task.

ScheduleExhausted

A schedule no longer has a future execution.

Fields

label: String

Cron expression identifying the task.

LoopFailed

A scheduler loop terminated unexpectedly.

Fields

label: String

Cron expression identifying the task.

message: String

Runtime failure description.

Trait Implementations

impl Clone for SchedulerError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchedulerError

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

Formats the value using the given formatter.

impl Display for SchedulerError

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

Formats the value using the given formatter.

impl Eq for SchedulerError

impl Error for SchedulerError

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<SchedulerError> for ServerError

fn from(source: SchedulerError) -> Self

Converts to this type from the input type.

impl PartialEq for SchedulerError

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

Equality operator ==.

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

Inequality operator !=.
