Struct Counters 

#[non_exhaustive]
pub struct Counters {
    pub announced: AtomicU64,
    pub announced_closed: AtomicU64,
    pub subscriptions: AtomicU64,
    pub subscriptions_closed: AtomicU64,
    pub broadcasts: AtomicU64,
    pub broadcasts_closed: AtomicU64,
    pub bytes: AtomicU64,
    pub frames: AtomicU64,
    pub groups: AtomicU64,
}

Cumulative atomic counters for a single (tier, role) on a broadcast.

Every field is bumped from a RAII guard: the open counters on construction and their _closed counterparts on drop. broadcasts / broadcasts_closed are the per-(broadcast, session) subscription sentinel driven by SessionBroadcasts (the first active subscription a session opens for the broadcast bumps broadcasts, the last to close bumps broadcasts_closed), so summed across sessions broadcasts - broadcasts_closed is the count of distinct sessions currently subscribed.

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.
