Enum DistributionConfig 

#[non_exhaustive]
pub enum DistributionConfig {
    Exponential {
        rate: f64,
    },
    Normal {
        mean: f64,
        stddev: f64,
    },
    Uniform {
        min: f64,
        max: f64,
    },
}

Distribution model configuration for histogram and summary generators.

Determines how sample values are distributed when the generator produces observations on each tick. Deserialized from YAML via the type tag.

Example YAML

distribution:
  type: exponential
  rate: 10.0

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exponential

Exponential distribution with rate parameter lambda.

Mean = 1/lambda. Models latency distributions.

Fields

rate: f64

Rate parameter (lambda). Must be strictly positive.

Normal

Normal (Gaussian) distribution.

Fields

mean: f64

Center of the distribution.

stddev: f64

Spread of the distribution. Must be strictly positive.

Uniform

Uniform distribution over [min, max].

Fields

min: f64

Lower bound (inclusive).

max: f64

Upper bound (inclusive).
