Struct Registry 

pub struct Registry { /* private fields */ }

Counter collection, re-exported from moq_net::stats so stats consumers can depend on this crate alone. Counter collection registry. Cheap to clone (Arc inside for the shared state). One instance per relay; sessions get tier-scoped handles via Registry::tier. The moq-stats crate drains it with Registry::report to publish the counters as MoQ broadcasts.

Implementations

impl Registry

pub fn new(config: Config) -> Registry

Build an enabled registry from config.

pub fn disabled() -> Registry

Build a no-op registry: every handle is empty and all bumps are dropped.

pub fn exclude(&self) -> &Patterns

The excluded patterns. See Config::exclude.

pub fn tier(&self, tier: Tier) -> Handle

Returns a tier-scoped handle. Bumps through this handle land in the tier’s counters.

pub fn snapshot(&self) -> Snapshot

Take a host-level Snapshot: every counter summed across all tracked broadcasts, split by tier and role, plus per-tier session presence. Briefly takes the entry then the session locks. Returns an all-zero snapshot for a disabled registry.

Unlike Registry::report, this collapses per-broadcast detail into node totals (what a /metrics-style scrape wants) and never prunes.

pub fn report(&self, report: &mut Report)

Refill report with the per-broadcast detail and prune dead entries.

Clears report, keeping its capacity so a caller draining on an interval reuses one report instead of allocating per drain, then fills every (broadcast, tier) traffic readout and every (tier, root) session gauge. Entries no guard references anymore are then dropped (their final values are still in the report, so a publisher draining on an interval emits the closing readout exactly once). A pruned path that sees traffic again restarts from zero; see the module docs on counter resets. Leaves the report empty for a disabled registry.

Trait Implementations

impl Clone for Registry

fn clone(&self) -> Registry

impl Default for Registry

fn default() -> Registry

A disabled (no-op) registry; see Registry::disabled.
