Struct SamplingInfo 

Source 
pub struct SamplingInfo {
    pub sampled: bool,
    pub final_sample_rate: f64,
    pub min_sample_rate: f64,
    pub reservoir_size: usize,
    pub results_collected: usize,
}
Expand description

Describes the VU-threshold + reservoir sampling state at end of run.

Consumers should display a disclaimer when sampled == true, as percentile values are based on a random sample of the full request population.

Fields§

§sampled: bool

true if min_sample_rate < 1.0 at any point during the run.

§final_sample_rate: f64

VU-threshold sample rate at end of run (1.0 = no threshold active).

§min_sample_rate: f64

Lowest sample rate observed; drives the “percentiles are approximate” warning.

§reservoir_size: usize

Configured reservoir cap (--result-buffer).

§results_collected: usize

Actual results in the reservoir buffer (≤ reservoir_size).
