DispatchOutcome

Enum DispatchOutcome 

Source
pub enum DispatchOutcome {
    Fresh,
    Duplicate,
    NoSagaBypass,
    Unrecognized,
}
Expand description

Outcome of dispatch_host_command: tells the caller whether the dispatch was a fresh execution (action ran, Report was inserted

  • sent) or a duplicate (Report was re-sent from cache, action did NOT re-run).

Variants§

§

Fresh

First-time dispatch: action executed, cached Report sent.

§

Duplicate

Duplicate dispatch: cached Report re-emitted, no action.

§

NoSagaBypass

Command had no saga_id (or saga_id == 0, the “no-saga” sentinel) — the LRU is bypassed and the action runs unconditionally. This branch is mostly defensive: the launcher’s CPD-3 wiring always issues with a real saga_id, but a stray legacy / forward-compat dispatch could hit this.

§

Unrecognized

Command kind isn’t a known host-bound saga payload (e.g. the reader received a Report* echo that should never have been sent down to the host). Logged at warn; no action, no reply.
