Struct CronExpr 

pub struct CronExpr { /* private fields */ }

Implementations

impl CronExpr

pub fn parse(input: &str) -> Result<Self, String>

Parse a 5-field cron expression. Rejects extended syntax.

pub fn as_str(&self) -> &str

The original expression, e.g. "*/5 * * * *".

pub fn next_after(&mut self, after: DateTime<Utc>) -> Option<DateTime<Utc>>

Compute the next fire time strictly after after.

Cron expressions are interpreted in the host’s local timezone (matching the Claude Code /loop spec). The returned fire time is stored as DateTime<Utc> so persisted task records stay timezone- independent.

pub fn approx_interval_seconds(&mut self) -> i64

Approximate interval between consecutive fires, used for jitter sizing.
