Struct Tier 

pub struct Tier(/* private fields */);

Traffic-class label that selects which counter set a session’s bumps record in, so a single Registry can split customer-facing, cluster-peer, regional, etc. traffic. Each tracked broadcast keeps a per-tier counter set on both its publisher and subscriber sides.

The default tier (Tier::default) is unprefixed: its published tracks are publisher.json, subscriber.json, and sessions.json. A named tier prefixes every track with its label, so Tier::new("region/sjc") records on region/sjc/publisher.json. The label is an arbitrary path chosen by business logic; an empty label is the default tier.

Implementations

impl Tier

pub fn new(label: impl Into<PathOwned>) -> Self

A tier with the given label. An empty label is the default tier.

pub fn label(&self) -> &PathOwned

The tier label, empty for the default tier.

pub fn is_default(&self) -> bool

True for the default (unprefixed) tier.

pub fn track_name(&self, name: &str) -> String

Track name for this tier: name on the default tier, else <tier>/<name>. This is the naming rule the published stats tracks follow.

pub fn as_str(&self) -> &str

The tier label as used in metrics: empty ("") for the default tier, otherwise the label (e.g. "region/sjc"). Mirrors the wire convention, where the default tier is unprefixed and named tiers are <label>/-prefixed.
