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 control(&self) -> Vec<(Tier, Control, Bytes)>

The (tier, class, totals) control-message rows with any traffic, sorted by tier and class. Includes prefixes inside complete codec values, but excludes separately coded type selectors, media payload, and transport framing, acknowledgements, and retransmissions.

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.
