Struct Presence 

#[non_exhaustive]
pub struct Presence {
    pub sessions: u64,
    pub sessions_closed: u64,
}

Connected-session presence for one slice (an auth root on a tier, or any sum of such slices): cumulative connects and disconnects. sessions - sessions_closed is the current live session count.

Like Traffic, this is also the wire shape of one entry on a published sessions track, so it derives both serde directions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

sessions: u64

Cumulative sessions connected.

sessions_closed: u64

Cumulative sessions disconnected.
