CronCore

Struct CronCore 

Source
pub struct CronCore { /* private fields */ }
Expand description

Pattern-periodic compute core: a tick m ≥ 1 fires iff m mod cycle ∈ offsets. Structurally an interval with a match set — a cron expression’s shape. The match count in (cursor, now] is computed arithmetically, so a large now jump is O(offsets).

Implementations§

Source§

impl CronCore

Source

pub fn new(cycle: u64, offsets: impl IntoIterator<Item = u64>) -> Self

offsets are reduced mod cycle, sorted, and deduped. cycle is clamped to ≥ 1; empty offsets means the source never fires.

Source

pub fn count(&self) -> u64
