Enum Execution 

pub enum Execution<A: Aggregate, P, const N: usize> {
    Ignored,
    Executed {
        position: P,
        events: Events<EventOf<A>, N>,
    },
}

Outcome of one CommandRepository::execute — the aggregate-side dual of Reaction.

Two variants, exactly mirroring Handle::handle’s own Option: a no-op decision persists nothing and has no position; an accepted command’s events are durable and carry the $all position they landed at.

#[must_use]: the Executed position is the read-your-writes token — a caller that reads its own write back needs it (#330).

Variants

Ignored

Handle::handle returned Ok(None) — accepted, decided nothing. No append was issued, so root keeps its version, no GlobalSeq is burned, and there is no position. Read the unchanged state off root.

Executed

The command was accepted and its events are durable.

Fields

position: P

The $all position the last decided event landed at — the read-your-writes token. A projection whose checkpoint has reached it has necessarily observed this whole append.

events: Events<EventOf<A>, N>

The decided events, for inspection.
