Why Generation::run_until_retired returned.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Idle

No session lease was held.

DrainExpired

The drain limit expired while leases were still held. Admission is closed; the application decides how to end the remaining sessions.

Fields

active: usize

Session leases still held at retirement.

legacy: usize

Of those, sessions using a legacy protocol.
