Struct SelectorInput 

pub struct SelectorInput<T> {
    pub id: String,
    pub content: T,
    pub size: usize,
    pub score: f32,
    pub category: Option<String>,
    pub information_gain: Option<f32>,
    pub rank_score: Option<f64>,
}

A single input item to a selector operation.

Fields

id: String

Stable string identifier for deterministic tie-breaking.

content: T

The item payload carried through selection.

size: usize

Size in the unit of the caller’s budget (tokens, bytes, count).

score: f32

Pre-computed relevance score.

category: Option<String>

Optional category for diversity and category-weight scoring.

information_gain: Option<f32>

Pre-computed information gain (KL divergence proxy) for this candidate.

Defaults to 0.0 when None. Only affects selection when SelectorWeights.epistemic_weight > 0.0. See crates/khive-fold/docs/design.md#adr-024-bayesian-extensions-selector-budget-packing-and-precision-weighted-scoring for why this is caller-supplied rather than computed by the Selector.

rank_score: Option<f64>

Higher-precision pre-conversion effective score used for rank comparisons, when available.

When None, ranking widens score back to f64 via DeterministicScore::from_f32. Does not affect min_score filtering, which always operates on score. category_weights multipliers scale rank_score by the same weight applied to score. See crates/khive-fold/docs/api/selector.md#rank-score-precision-pr-535 for why callers need this instead of relying on the narrowed score field.
