Enum SampleSize 

pub enum SampleSize {
    RowCount(usize),
    Percentage(f64),
    Adaptive,
}

Sample size specification

Variants

RowCount(usize)

Exact number of rows to sample

Percentage(f64)

Percentage of table (0.0 to 1.0)

Adaptive

Automatically determine sample size based on table size

Strategy:

• Small tables (< 1000 rows): No sampling, use all rows
• Medium tables (1K-100K rows): 10% sample
• Large tables (> 100K rows): Fixed 10K row sample

Trait Implementations

impl Clone for SampleSize

fn clone(&self) -> SampleSize

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SampleSize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SampleSize

fn eq(&self, other: &SampleSize) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
