Available on crate feature decode only.

What a trigger capture watches, judges, and keeps.

Fields

selectors: Vec<String>

Full wire selectors to retain and record. The rules’ own selectors are watched too; the header names the union (O5).

pre: Duration

How far back the retained window reaches: the pre-roll asked for.

post: Duration

How long to keep recording after the trigger.

rules: Vec<Condition>

The rules; the first transition to firing on any of them fires the capture.

tick: Duration

Evaluation cadence — the watchdog’s --every.

timeout: Duration

Per-ask timeout: the roster and doctor sweeps, and the preamble GET.

give_up: Option<Duration>

Stop waiting after this long with nothing fired; None waits until the caller stops the future.

preamble: Option<PreambleSemantics>

What the preamble is a snapshot of; None writes no preamble at all.

max_samples: Option<u64>

Stop the post-roll after this many observed samples (the pre-roll and the preamble never count towards it).

max_replies: usize

Replies kept per preamble GET (#339); what the bound cost rides the header’s incomplete.
