LongHoldMiddleware

mlua_swarm::middleware

Struct LongHoldMiddleware 

Source 
pub struct LongHoldMiddleware {
    pub default_hold: Duration,
    pub event_tx: Sender<Event>,
}
Expand description

Base layer that emits Event::TaskAttemptCompleted with a long_hold_warn marker when a spawn’s completion takes longer than default_hold. Purely observational — it never alters the signal or blocks completion.

Fields§

§default_hold: Duration

Threshold above which a completion is flagged as long-held.

§event_tx: Sender<Event>

Broadcast sender the EventLog subscribes to.

Implementations§

Source§

impl LongHoldMiddleware

Source

pub fn new(default_hold: Duration, event_tx: Sender<Event>) -> Self

Sets the hold threshold and the event sender to warn through.

Trait Implementations§

Source§

impl SpawnerLayer for LongHoldMiddleware

Source§

fn wrap(&self, inner: Arc<dyn SpawnerAdapter>) -> Arc<dyn SpawnerAdapter> ⓘ

Wraps inner in this layer’s behaviour, returning a new SpawnerAdapter that delegates to inner (directly or via wrap_join) while adding this layer’s cross-cutting effect.
