Struct DrawSpec 

pub struct DrawSpec {
    pub categories: Vec<String>,
    pub category_pct: BTreeMap<String, f64>,
    pub subset_floor: Option<usize>,
}

2026-09-26: Sampling configuration.

Fields

categories: Vec<String>

2026-09-26: Categories to include. Empty means every single-turn subset, including the uncategorised live_relevance.

category_pct: BTreeMap<String, f64>

2026-09-26: Per-category percentage. A selected subset whose category has no entry is taken whole.

subset_floor: Option<usize>

2026-09-26: A subset of at most this many rows is taken in full, bypassing the percentage, so live_parallel (16 rows) is not cut to one to three samples.

Implementations

impl DrawSpec

pub fn golden() -> Self

2026-09-26: The golden MLPerf-edge draw: the three categories at 62/10/10 with a floor of 25. On reference_subset_totals this is 995.

pub fn full() -> Self

2026-09-26: Every sample of the three scored categories, no sampling. The same categories as golden: taking live_relevance too would move overall_accuracy on a subset no category scores.

pub fn echolp() -> Self

2026-09-26: The echolp draw: the three categories at 46/23/12 with a floor of 25. On reference_subset_totals this is 1004. It weights live more than twice as heavily as golden (23 % vs 10 %), so a score from one draw is not comparable to a threshold from the other; each has its own baseline.

pub fn mini() -> Self

2026-10-03: The mini draw for a model’s cheap correctness suite: the golden draw’s three categories at about a fifth of its rates (12.5/2/2) with a floor of 5, so the category mix stays close to golden. On reference_subset_totals this is MINI_SAMPLES. Not comparable to golden or echolp; it carries its own floors.

pub fn includes(&self, subset: &str) -> bool

2026-09-26: Whether this subset is in the selection.

pub fn take_count(&self, subset: &str, total: usize) -> usize

2026-09-26: How many rows to keep from a subset holding total rows.

Trait Implementations

impl Clone for DrawSpec

fn clone(&self) -> DrawSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawSpec

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

Formats the value using the given formatter.

impl PartialEq for DrawSpec

fn eq(&self, other: &DrawSpec) -> 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.
