Struct LineItemSampler 

pub struct LineItemSampler { /* private fields */ }

Sampler for journal entry line item counts.

Produces realistic line item counts based on empirical distributions from real-world general ledger data.

Implementations

impl LineItemSampler

pub fn new(seed: u64) -> Self

Create a new sampler with default configuration.

pub fn with_config( seed: u64, line_config: LineItemDistributionConfig, even_odd_config: EvenOddDistributionConfig, debit_credit_config: DebitCreditDistributionConfig, ) -> Self

Create a sampler with custom configuration.

pub fn sample_count(&mut self) -> usize

Sample a line item count.

pub fn sample_even(&mut self) -> bool

Sample whether the count should be even.

pub fn sample_count_with_parity(&mut self) -> usize

Sample a line item count with even/odd constraint.

When adjustment is needed, randomly chooses to increment or decrement to avoid biasing toward lower counts.

pub fn sample_debit_credit_type(&mut self) -> DebitCreditSplit

Sample the debit/credit split type.

pub fn sample(&mut self) -> LineItemSpec

Sample a complete line item specification.

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

Reset the sampler with the same seed.
