Implementations§

Source§

impl CronParser

Source

pub fn next_execution( cron_expr: &str, from_utc: DateTime<Utc>, timezone: &str, ) -> Result<DateTime<Utc>>

Compute next execution time for a cron expression.

  • cron_expr: standard 5/6-field cron expression supported by cron crate
  • from_utc: “now” moment as UTC
  • timezone: tz name like “UTC”, “Asia/Kolkata”

Returns next run time in UTC.

Source

pub fn validate(cron_expr: &str) -> Result<()>

Convenience: validate cron expr

Source

pub fn parse_tz(timezone: &str) -> Result<Tz>

Parse a tz string into chrono_tz::Tz

Source

pub fn to_tz(ts_utc: DateTime<Utc>, tz: Tz) -> DateTime<Tz>

Helper: convert UTC timestamp to tz DateTime
