Struct CronExpression 

pub struct CronExpression { /* private fields */ }

A structure representing a cron expression with advanced features like timezones, exclusion rules, and jitter.

Use CronExpression::builder() to create a new instance fluently.

Implementations

impl CronExpression

pub fn builder() -> Self

Create a new builder for a CronExpression.

pub fn with_timezone(self, tz: Tz) -> Self

Set a fixed timezone for this schedule.

pub fn with_jitter(self, max_jitter: Duration) -> Self

Adds a random jitter to the execution time.

The job will run at the scheduled time plus a random duration between 0 and max_jitter.

pub fn exclude_date(self, date: NaiveDate) -> Self

Exclude specific dates from the schedule.

pub fn exclude_dates(self, dates: Vec<NaiveDate>) -> Self

Exclude a list of dates.
