EffectFinality

Enum EffectFinality 

Source
pub enum EffectFinality {
    NotAttempted,
    Initiated,
    Finalized,
    Failed,
    Indeterminate,
}
Expand description

How far a state change actually got. Orthogonal to EffectConfidence, which grades the evidence: an effect can be Finalized with weak evidence, or Initiated with excellent evidence that it is still pending.

Collapsing the two is a real production failure, not a theoretical one. A receipt that reports a single success: true can be accurate in every field and false as a composite: the write was accepted, acknowledged, assigned an id, and served back on read – and never committed. Every predicate held; “done” did not. Separating the axes is what makes that claim expressible, and the verify_effect cap on Finalized is what makes it checkable.

Variants§

§

NotAttempted

Authority was exercised but no state change was attempted – a timeout or refusal before the call went out. This is the “no authority moved” receipt: an explicit signed negative, so absence stops being indistinguishable from a check that was never required.

§

Initiated

The target accepted the change but has not confirmed it as final. Unresolved: an acknowledgement is not a commit.

§

Finalized

The target confirmed the change is final.

§

Failed

Attempted, and definitively did not take effect.

§

Indeterminate

Attempted; whether it took effect could not be established. Distinct from Initiated, where the target at least said yes-but-not-yet. Here nobody knows, which is a state to escalate from, not to retry blindly.

Implementations§

Source§

impl EffectFinality

Source

pub fn is_resolved(self) -> bool

Whether the lifecycle reached a terminal state. Initiated and Indeterminate are open: something is still owed. Only open effects can breach a resolution deadline.
