Implementations§

Source§

impl TaskInfoCache

Source

pub fn new(cap: usize) -> Arc<Self> ⓘ

Cache holding at most cap tasks.

Source

pub fn on_submit(&self, id: u64, meta: TaskMeta)

Record a submission (not for duplicates: the original details stay).

Source

pub fn on_event(&self, ev: &StatusEvent, pool: &Arc<str>, at_ns: i64)

Record a status event of a task in pool, observed at at_ns (Unix ns).

Source

pub fn get(&self, id: u64) -> Option<TaskMeta>

Details of a task.

Source

pub fn list_finished( &self, pools: &[&str], statuses: &[TaskStatus], after: u64, limit: usize, ) -> Vec<(u64, TaskMeta)>

Finished tasks in id order: those in one of pools (any if empty) with one of statuses (any finished status if empty) and ids above after, at most limit.

Source

pub fn id_for_key(&self, key: &str) -> Option<u64>

Latest task id seen for key.
