Enum AdvancedAmountSampler 

pub enum AdvancedAmountSampler {
    LogNormal(LogNormalMixtureSampler),
    Gaussian(GaussianMixtureSampler),
    Pareto(ParetoSampler),
}

Advanced amount sampler wrapping one of the supported distribution families. Callers keep their existing legacy [AmountSampler](super:: AmountSampler) and only consult this wrapper when distributions.amounts.enabled (or another advanced sub-block like distributions.pareto.enabled) is true.

v3.4.4 added the Pareto variant for heavy-tailed monetary samples (capex, strategic contracts, fraud amounts).

Variants

LogNormal(LogNormalMixtureSampler)

Log-normal mixture (preferred for positive monetary amounts).

Gaussian(GaussianMixtureSampler)

Gaussian mixture (useful for signed quantities like deltas).

Pareto(ParetoSampler)

Pareto heavy-tailed distribution (v3.4.4+).

Implementations

impl AdvancedAmountSampler

pub fn new_log_normal( seed: u64, config: LogNormalMixtureConfig, ) -> Result<Self, String>

pub fn new_gaussian( seed: u64, config: GaussianMixtureConfig, ) -> Result<Self, String>

Create a Gaussian-mixture sampler.

pub fn new_pareto(seed: u64, config: ParetoConfig) -> Result<Self, String>

Create a Pareto sampler (v3.4.4+).

pub fn sample_decimal(&mut self) -> Decimal

Sample one amount as Decimal.

pub fn reset(&mut self, seed: u64)

Reset the underlying RNG.
