Implementations§

Source §

impl PostgresScheduler

Source

pub fn new(pool: PgPool) -> Self

Source

pub async fn claim_for_worker( &self, lane: &LaneId, worker_id: &WorkerId, worker_instance_id: &WorkerInstanceId, worker_capabilities: &BTreeSet<String>, grant_ttl_ms: u64, ) -> Result<Option<ClaimGrant>, EngineError>

Find an eligible execution, admit it against budget + quota, and issue a signed ClaimGrant. Returns Ok(None) when no candidate is admissible on this lane right now.
