Struct Sampler 

pub struct Sampler { /* private fields */ }

Implementations

impl Sampler

pub async fn new( pool: &PgPool, schema: &str, table: &str, estimated_rows: Option<i64>, sample_size: usize, ) -> Result<Self, Error>

Create a new sampler with auto select strat

pub fn with_strategy(strategy: SamplingStrategy) -> Self

Create a sampler with a specific strat

pub fn show_progress(self, enabled: bool) -> Self

Enable or disable prog bar

pub async fn sample( &self, pool: &PgPool, schema: &str, table: &str, column: &str, ) -> Result<Vec<Value>, Error>

Production safety

In prod mode:

• Max 1% sampling for large tables
• Requires explicit confirmation (future work)
• shows estimated query

pub fn strategy_info(&self) -> String

Get information about the sampling strategy
