Enum AttentionKind 

pub enum AttentionKind {
    ResultAvailable,
    ReviewRejected,
    StepFailed,
    Blocked,
    HumanDecisionRequested,
    DeadlineExceeded,
    InactivityDetected,
    InterventionRequested,
    CeremonyEnded,
}

Why a ceremony is worth the integrator’s attention.

A closed list, because the loop’s stopping rules are written over it: a kind the engine cannot name is a kind an integrator cannot be told to stop for.

Variants

ResultAvailable

A step produced a result the integrator can take up.

ReviewRejected

A completed step’s own output says it was not accepted.

StepFailed

A step failed or ran out of time.

Blocked

The ceremony cannot move without something outside it.

HumanDecisionRequested

A human guard needs a person, or a person has just answered one.

DeadlineExceeded

A ceremony or state deadline passed.

InactivityDetected

Nothing has happened for longer than the policy tolerates.

InterventionRequested

A supervisor asked a question of whoever is working.

CeremonyEnded

The ceremony reached a terminal phase.

Implementations

impl AttentionKind

pub const ALL: [Self; 9]

Every kind, which is also the default policy’s selection.

pub fn from_label(label: &str) -> Option<Self>

The kind a derived identity ends with, when it ends with one.

AttentionEventId::derive spells the kind into the identity, and the ledger holds that identity rather than the event. Reading it back is what lets a queue be weighed — which of the things waiting may be dropped — without keeping a second copy of what each delivery is about.

pub const fn as_str(self) -> &'static str

pub const fn is_blocking(self) -> bool

Whether dropping this kind under overflow would lose a decision.

Overflow discards the oldest item that nobody is waiting on. A human decision, a block or the end of a ceremony are things the loop stops for, so they are never the ones discarded.
