Struct IptExperience 

Source 
struct IptExperience {
    duration: Duration,
    outcome: Result<(), RetryTime>,
}
Expand description

How things went last time we tried to use this introduction point

Neither this data structure, nor Data, is responsible for arranging that we expire this information eventually. If we keep reconnecting to the service, we’ll retain information about each IPT indefinitely, at least so long as they remain listed in the descriptors we receive.

Expiry of unused data is handled by state.rs, according to last_used in ServiceState.

Choosing which IPT to prefer is done by obtaining an IptSortKey (from this and other information).

Fields§

§duration: Duration

How long it took us to get whatever outcome occurred

We prefer fast successes to slow ones. Then, we prefer failures with earlier RetryTime, and, lastly, faster failures to slower ones.

§outcome: Result<(), RetryTime>

What happened and when we might try again

Note that we don’t actually enforce the RetryTime here, just sort by it using RetryTime::loose_cmp.

We do return an error that is itself HasRetryTime and expect our callers to honour that.
