Struct FaithfulnessScore 

pub struct FaithfulnessScore {
    pub precision: f32,
    pub polarity_match: bool,
    pub unentailed: Vec<String>,
    pub polarity_drift: Vec<PolarityDrift>,
}

A faithfulness score for a rendered hypothesis against its source.

Fields

precision: f32

Fraction of hypothesis content tokens entailed by source. [0.0, 1.0].

polarity_match: bool

True iff polarity-token multisets match exactly between source and hypothesis.

unentailed: Vec<String>

Hypothesis content tokens not entailed by source (hallucinated words).

polarity_drift: Vec<PolarityDrift>

Polarity tokens whose counts differ between hypothesis and source. Empty iff polarity_match is true.

Implementations

impl FaithfulnessScore

pub fn is_faithful(&self) -> bool

True iff precision == 1.0 AND polarity_match. Use this for strict template conformance tests where zero hallucination is required.

pub fn passes(&self, threshold: f32) -> bool

True iff precision >= threshold AND polarity_match. Use for runtime gates that tolerate a small fraction of unentailed tokens — e.g. hedged phrasings that legitimately introduce words not in the input context.

Trait Implementations

impl Clone for FaithfulnessScore

fn clone(&self) -> FaithfulnessScore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FaithfulnessScore

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

Formats the value using the given formatter.

impl PartialEq for FaithfulnessScore

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