Struct SeriesRow 

pub struct SeriesRow {

    pub name: String,
    pub key: String,
    pub origin: String,
    pub producer: String,
    pub class: String,
    pub subject: String,
    pub labels: BTreeMap<String, String>,
    pub field: Option<String>,
    pub kind: Option<String>,
    pub unit: Option<String>,
    pub value: Option<f64>,
    pub last_seen_unix_s: u64,
    pub state: SeriesState,
    pub samples: u64,
    pub drop_exposed: u64,
}

One exported series: a contract-derived identity, its last value, and the state that says whether the value is current.

Fields

name: String

The metric name the exposition uses — derived from the registry’s producer, pattern, unit and kind, never from the leaf’s spelling.

key: String

The concrete wire key this series was last fed from.

origin: String

producer: String

class: String

subject: String

The declared pattern, e.g. disk/{mount}/used.

labels: BTreeMap<String, String>

The {var} bindings by their declared names.

field: Option<String>

The top-level field this series reads, when the payload was an object carrying several numerics rather than one leaf value.

kind: Option<String>

The declared kind token, when the registry declares one.

unit: Option<String>

The declared unit, verbatim, when the registry declares one.

value: Option<f64>

The newest value seen. Absent when the state says the series stopped — a stopped series exposes its state and its labels, never a stale number that reads as current.

last_seen_unix_s: u64

When the newest sample arrived, unix seconds on the observer’s clock — captured at ingest, so it does not move between scrapes.

state: SeriesState

samples: u64

Samples folded into this series since the observer started.

drop_exposed: u64

Folds during which this series was fed and the observer dropped samples — the interval where its value may not be the newest.
