Struct WeibullConfig 

pub struct WeibullConfig {
    pub shape: f64,
    pub scale: f64,
    pub min_value: f64,
    pub max_value: Option<f64>,
    pub round_to_integer: bool,
}

Configuration for Weibull distribution.

Fields

shape: f64

Shape parameter (k) - controls the shape of the distribution. k < 1: decreasing failure rate (early failures more likely) k = 1: constant failure rate (exponential distribution) k > 1: increasing failure rate (wear-out failures)

scale: f64

Scale parameter (lambda) - controls the characteristic life. 63.2% of values will be below this threshold.

min_value: f64

Minimum value (shifts the distribution).

max_value: Option<f64>

Maximum value (clamps output).

round_to_integer: bool

Whether to round to integers (useful for days).
