Struct ScoreWeightedSelector 

pub struct ScoreWeightedSelector;

Stateless selector that picks the highest-scoring ScoredCandidate.

Ties are broken by registration order (the first candidate in the input vector wins). An empty input returns None.

Example

use stygian_plugin::reliability::{ReliabilityScore, ScoreWeightedSelector, ScoredCandidate};

let candidates = vec![
    ScoredCandidate::new("primary", ReliabilityScore::from_overall(0.6)),
    ScoredCandidate::new("plugin", ReliabilityScore::from_overall(0.9)),
];
let winner = ScoreWeightedSelector::pick_best(candidates).unwrap();
assert_eq!(winner.name, "plugin");

Implementations

impl ScoreWeightedSelector

pub fn pick_best(candidates: Vec<ScoredCandidate>) -> Option<ScoredCandidate>

Pick the highest-scoring candidate. Returns None for an empty input.

The first candidate with the maximum score wins on ties — this preserves the registration order so callers retain deterministic control over tie-breaking.

pub fn pick_best_ref(candidates: &[ScoredCandidate]) -> Option<&ScoredCandidate>

Pick the highest-scoring candidate by reference. Useful when the caller already owns the candidates and does not want to move them.
