Struct Labels 

pub struct Labels {
    pub pipeline: Arc<str>,
    pub row: Arc<str>,
    pub run_id: Arc<str>,
}

Common labels carried by every span and metric.

pipeline and row are Prometheus labels (bounded cardinality). run_id is a span attribute only — never a metric label — used for trace correlation. connector is captured per-decorator at construction time, not stored here.

Fields

pipeline: Arc<str>

row: Arc<str>

run_id: Arc<str>

Implementations

impl Labels

pub fn new( pipeline: impl Into<Arc<str>>, row: impl Into<Arc<str>>, run_id: impl Into<Arc<str>>, ) -> Self

pub fn for_named(pipeline: impl Into<Arc<str>>) -> Self

Convenience constructor for non-CLI library callers: pipeline name only, empty row, freshly-minted UUIDv7 run id.

Trait Implementations

impl Clone for Labels

fn clone(&self) -> Labels

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Labels

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
