Struct ScoreSet32 

pub struct ScoreSet32<C> { /* private fields */ }

Builder for a weighted set of Metric32s.

ScoreSet32 collects metrics with raw weights, normalizes them, and produces a closure — either a weighted-sum function or a breakdown iterator.

Examples

let scorer = ScoreSet32::new()
    .push(2.0, gc_metric)?
    .push(1.0, len_metric)?
    .sum()?;

let total: f32 = scorer(&ctx);

Implementations

impl<C> ScoreSet32<C>

pub fn new() -> Self

Create an empty score set builder.

pub fn push( self, weight: f32, metric: Metric32<C>, ) -> Result<Self, &'static str>

Add a metric with a raw (unnormalized) weight.

The weight must be finite and strictly positive. Normalization happens when sum or breakdown is called.

pub fn sum(self) -> Result<impl Fn(&C) -> f32, &'static str>

Consume the builder and return a weighted-sum closure.

Normalizes all weights so they sum to 1, then returns a closure impl Fn(&C) -> f32 that evaluates every metric against the context and returns the weighted sum.

Errors

Returns an error if the set is empty or if weight normalization fails.

pub fn breakdown( self, ctx: &C, ) -> Result<impl IntoIterator<Item = Breakdown32>, &'static str>

Consume the builder and return per-metric Breakdown32 rows.

Normalizes all weights so they sum to 1, evaluates every metric against ctx, and returns the result as impl IntoIterator. The returned value owns all data — no lifetime coupling to ctx — so it can be passed out of local scopes freely.

Use directly in a for loop or call .into_iter().

Errors

Returns an error if the set is empty or if weight normalization fails.
