Crate score_set 

score-set

A Rust library for building static weighted scoring operator sets.

It does not prescribe a unified input or context type. Instead it declares, stores, normalizes, and combines a set of weighted operators — scoring is done via a user-provided closure that can inject arbitrary runtime data.

Quick example

use score_set::*;

let gc = metric("gc")
    .measure().by(|dna: &&str| gc_ratio(dna))
    .map01().by(|raw: &f64, _: &&str| Value01::witness(*raw).unwrap());

let len = metric("len")
    .measure().by(|len: &usize| *len)
    .map01().by(|raw: &usize, _: &usize| {
        Value01::witness((*raw as f64 / 100.0).min(1.0)).unwrap()
    });

let ms = score_set! {
    2.0 => gc,
    3.0 => len,
}?;

let dna = "ACGTACGT";
let score = ms.score().by(|(gc, len)| {
    gc.contribute(gc.metric().eval(&dna))
        + len.contribute(len.metric().eval(&dna.len()))
});

Macros

score_set

Declare a set of weight => metric pairs.

Structs

GtZero

Witness credential for a value validated to be finite and strictly > 0.

Member

A member of a MetricSet: a normalized weight paired with its metric.

Metric

A scoring operator built via the measure().by() → map01().by() pipeline.

NormalizedContainer

Witness credential for a container validated as a complete set of normalized weights (each in [0, 1], sum to 1).

NormalizedWeight

Witness credential for a single normalized weight.

ScoreSet

A static weighted set of scoring operators with normalized weights.

ScoreStage

The scoring stage, created by ScoreSet::score.

Value01

Witness credential for a value validated to be finite and in [0, 1].

Witnessed

Traits

Float

Public trait bound for floating-point types used throughout score-set.

WitnessExt

Extension trait for starting a witnessing pipeline.

Functions

metric

Entry point: metric("name").
