Struct RunSummary 

pub struct RunSummary {
    pub run_id: RunId,
    pub event_count: u64,
    pub first_recorded_at: OffsetDateTime,
    pub last_recorded_at: OffsetDateTime,
}

A one-line-per-run projection of the log, returned by EventStore::list_runs.

Every field is a pure aggregate over the store’s queryable columns (COUNT, MIN, MAX), computed without parsing a single envelope or replaying anything. That is the reason the field set is small and stops where it does:

• run_id names the run. Required.
• event_count is how many events the run has, a cheap COUNT(*) and a useful “how far along” signal.
• first_recorded_at and last_recorded_at are the earliest and latest recorded timestamps, a MIN/MAX that gives a run’s start and its age or most recent activity.

Run status (running, suspended, completed, and so on) is deliberately absent. Status is a replay-time projection: you derive it by folding the log, not by reading a column. Putting it here would either require the store to parse and interpret events (which is the replay engine’s job) or to keep a denormalized status column in step with the log (a second source of truth). Both break the rule that the log is the only state, so status stays out of the store and lives in the replay layer that owns it.

The timestamps are reconstructed in UTC. Fidelity to the exact recorded offset lives in the stored envelope JSON; this summary normalizes to UTC because it exists for sorting and display, not for round-tripping.

Fields

run_id: RunId

The run this summary describes.

event_count: u64

How many events the run’s log holds.

first_recorded_at: OffsetDateTime

The earliest recorded timestamp in the run, in UTC.

last_recorded_at: OffsetDateTime

The latest recorded timestamp in the run, in UTC.
