Struct TriggerDeferral 

#[non_exhaustive]
pub struct TriggerDeferral {
    pub payload: String,
    pub delay: Option<Duration>,
}

Deferral marker returned by TriggerOutcome::Defer.

Carries an implementation-defined payload plus an optional delay (FU-5). When delay is None the deferred item re-fires on the next scheduler tick (legacy “any moment now” semantics); when Some(d) the host’s deferral queue waits at least d before re-invoking the trigger.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

payload: String

Implementation-defined payload — opaque to the host. Persisted across Uni restarts when the host’s durable defer queue is enabled.

delay: Option<Duration>

Wait at least this duration before re-firing. None means “as soon as the next tick fires” (~50–100 ms).

Implementations

impl TriggerDeferral

pub fn from_payload(payload: impl Into<String>) -> Self

Construct a deferral with no delay.

Use this when the trigger is simply asking “re-queue me for the next tick” — e.g., when an external prerequisite resource might become available at any moment.

pub fn after(payload: impl Into<String>, delay: Duration) -> Self

Construct a deferral with an explicit delay.

The host’s deferral queue waits at least delay before re-invoking TriggerPlugin::on_deferred (or, when the host has not adopted the on_deferred callback, TriggerPlugin::fire with the original MutationBatch).
