Struct HistogramScenarioConfig 

pub struct HistogramScenarioConfig {
    pub base: BaseScheduleConfig,
    pub buckets: Option<Vec<f64>>,
    pub distribution: DistributionConfig,
    pub observations_per_tick: Option<u64>,
    pub mean_shift_per_sec: Option<f64>,
    pub seed: Option<u64>,
    pub encoder: EncoderConfig,
}

Full configuration for a single histogram scenario run.

Embeds BaseScheduleConfig for the shared schedule and delivery fields, adding histogram-specific parameters: bucket boundaries, distribution model, observations per tick, mean shift, and seed.

Fields

base: BaseScheduleConfig

Shared schedule and delivery fields.

buckets: Option<Vec<f64>>

Histogram bucket upper bounds. When None, uses the default Prometheus bucket boundaries: [0.005, 0.01, 0.025, 0.05, 0.1, 0.25, 0.5, 1.0, 2.5, 5.0, 10.0].

distribution: DistributionConfig

Distribution model for generating observations.

observations_per_tick: Option<u64>

Number of observations to sample per tick. Defaults to 100.

mean_shift_per_sec: Option<f64>

Linear drift applied to the distribution center per second. Defaults to 0.0.

seed: Option<u64>

Determinism seed for the RNG. Defaults to 0.

encoder: EncoderConfig

Output encoder. Defaults to prometheus_text.
