Struct Trigger 

pub struct Trigger {
    pub state: TriggerState,
    pub kind: TriggerKind,
    pub eligible_at_ms: Option<i64>,
    pub interval_ms: Option<i64>,
}

A trigger’s schedulable state: everything due-ness and step need, and nothing about which ticket or project the demand points at. Targeting is a storage-side join; whether the demand is live is a decision.

Fields

state: TriggerState

kind: TriggerKind

eligible_at_ms: Option<i64>

interval_ms: Option<i64>

Implementations

impl Trigger

pub fn is_due(&self, now_ms: i64) -> bool

The definition of due-ness. The SQL scan in work_state::trigger carries a predicate that mirrors this so a large queue does not have to be read into memory to be filtered, but this function is the definition, and a test asserts the two agree over the whole matrix of kinds, states, and schedules.

A schedule-carrying kind with no eligible_at_ms is never due: an unscheduled at is a corrupt row, and answering “due” would fire it immediately, which is the opposite of what it asked for. That matches SQL, where NULL <= ? is not true.
