Module schedule 

CronSchedule – validated cron expression newtype.

Wraps croner::Cron to guarantee that any CronSchedule value holds a syntactically valid cron expression. Construction is fallible; once built the value is safe to pass to tokio_cron_scheduler without further validation.

A schedule also carries a SchedulePolicy: what to do with missed occurrences, with overlapping runs, and the timezone the expression is evaluated in.

Structs

Enums

CatchupPolicy
