Struct Snapshot 

#[non_exhaustive]
pub struct Snapshot { /* private fields */ }

A point-in-time, host-level rollup of a registry’s counters, returned by Registry::snapshot.

Every counter is summed across all broadcasts the registry is tracking and split by tier and role, plus per-tier connected-session presence. One entry per tier that recorded any traffic or session, keyed by the tier’s label (so an idle tier is simply absent). Intended for a scrape / /metrics-style endpoint where per-broadcast cardinality is unwanted; use Registry::report for the per-broadcast breakdown. A disabled registry yields no rows.

Implementations

impl Snapshot

pub fn traffic(&self) -> Vec<(Tier, Role, Traffic)>

The (tier, role, totals) traffic rows, one publisher and one subscriber row per tier present. Sorted by tier label then role for stable output.

pub fn sessions(&self) -> Vec<(Tier, Presence)>

The (tier, sessions) presence rows, one per tier present, sorted by tier label.
