Struct HistogramConfig 

pub struct HistogramConfig {
    pub boundaries: Vec<f64>,
}

Explicit bucket boundaries (in seconds) for latency histograms ({ns}.handshake.duration, {ns}.path.validation.duration).

Applied directly to the OTel Histogram instrument via f64_histogram(...).with_boundaries(...) — a version-stable API across the opentelemetry 0.27–0.32 line. (Base-2 exponential aggregation would need an SDK View; the View API is still in flux across these versions, so explicit boundaries are the supported choice for now.)

Fields

boundaries: Vec<f64>

Bucket upper bounds, seconds, ascending.
