Enum ScheduleError 

pub enum ScheduleError {
    EmptyCronExpression,
    CronParse {
        expression: String,
        source: CronParseError,
    },
    NoNextFireTime {
        expression: String,
    },
    ZeroInterval,
    IntervalOutOfRange,
    NextFireTimeOutOfRange,
}

Errors returned while validating or evaluating schedule triggers.

Variants

EmptyCronExpression

The supplied cron expression is empty or contains only whitespace.

CronParse

The supplied cron expression could not be parsed by the cron parser.

Fields

expression: String

The expression that failed validation.

source: CronParseError

Parser error returned by the underlying cron crate.

NoNextFireTime

The cron expression has no future matching timestamp.

Fields

expression: String

The expression whose next time could not be found.

ZeroInterval

Interval triggers must advance time by a positive duration.

IntervalOutOfRange

The supplied interval cannot be represented by chrono’s duration type.

NextFireTimeOutOfRange

Adding the interval to the reference timestamp overflowed.

Trait Implementations

impl Debug for ScheduleError

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

Formats the value using the given formatter.

impl Display for ScheduleError

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

Formats the value using the given formatter.

impl Error for ScheduleError

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<ScheduleError> for EngineError

fn from(error: ScheduleError) -> Self

Converts to this type from the input type.

impl From<ScheduleError> for ScheduleEvaluatorError

fn from(source: ScheduleError) -> Self

Converts to this type from the input type.
