Struct SamplingConfig 

pub struct SamplingConfig {
    pub sample_size: SampleSize,
    pub method: SamplingMethod,
    pub confidence_level: f64,
}

Configuration for statistical sampling

Fields

sample_size: SampleSize

Sample size strategy

method: SamplingMethod

Sampling method to use

confidence_level: f64

Statistical confidence level (e.g., 0.95 for 95% confidence)

Implementations

impl SamplingConfig

pub fn new(sample_size: SampleSize, method: SamplingMethod) -> Self

Create a new sampling configuration

pub fn adaptive() -> Self

Create configuration for adaptive sampling (default)

pub fn percentage(pct: f64) -> Self

Create configuration for percentage-based sampling

pub fn fixed(count: usize) -> Self

Create configuration for fixed-size sampling

pub fn determine_sample_size(&self, total_rows: usize) -> (usize, bool)

Determine actual sample size for a given table

Returns (sample_size, should_sample) tuple

• sample_size: Number of rows to sample
• should_sample: Whether sampling is needed (false for small tables)
