Struct ReachTrace 

pub struct ReachTrace {
    pub tries: usize,
    pub refused: usize,
    pub start_waited: Duration,
    pub retires_sent: usize,
    pub releases_seen: Vec<String>,
    pub answered_by: Option<String>,
    pub elapsed: Duration,
}

What: What the client did to reach a service that speaks its protocol and was started from its release. Why: The 17-second commit began with a service of another release being asked to retire; the tries, the wait for a start, the retires sent and the releases that answered tell that apart from a slow landing.

In TS you’d write (pseudocode):

type ReachTrace = { tries: number; refused: number; startWaited: number; retiresSent: number; releasesSeen: string[]; answeredBy?: string };

Fields

tries: usize

Connection attempts made, each one a connect call.

refused: usize

Attempts that found nothing listening or no greeting, which is the service being started by the manager.

start_waited: Duration

Time from the first attempt of a reach to the greeting, summed over the reaches that needed more than one attempt.

retires_sent: usize

Retire messages sent to services of another release.

releases_seen: Vec<String>

The release of every greeting, in the order received, without repeats.

answered_by: Option<String>

The release of the service that finally took the request.

elapsed: Duration

Time spent reaching, retire rounds included.
