Compose tiers, finest/freshest first.

Trait Implementations

impl MetricAccess for HybridStore

fn select_range( &self, matchers: &[Matcher], start_ms: i64, end_ms: i64, ) -> Result<Vector, QueryError>

Range selection: series matching every matcher, with every sample in [start_ms, end_ms] (ascending). Yields a range vector — the input a rollup (rate(m[w]), *_over_time) consumes. This is the one required method; select_instant derives from it.

fn select_instant( &self, matchers: &[Matcher], at_ms: i64, lookback_ms: Option<i64>, ) -> Result<Vector, QueryError>

Instant selection: series matching every matcher, each reduced to its latest sample within [at_ms - lookback, at_ms] (the PromQL stale-tolerance window; lookback_ms = None means a strict [at_ms, at_ms]). Yields an instant vector — one sample per series.
