Struct Presence 

#[non_exhaustive]
pub struct Presence {
    pub sessions_started: u64,
    pub sessions_ended: u64,
}

Counter collection, re-exported from moq_net::stats so stats consumers can depend on this crate alone. Connected-session presence for one slice (an auth root on a tier, or any sum of such slices): cumulative connects and disconnects. `sessions_started

• sessions_ended` is the current live session count.

Like Traffic, this is also the wire shape of one entry on a published sessions track. Serialize writes both the canonical names and the legacy sessions/sessions_closed spellings; deserialize accepts either, with the canonical name winning when both are present.

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_started: u64

Cumulative sessions connected.

sessions_ended: u64

Cumulative sessions disconnected.
