Struct ConfidenceInterval 

pub struct ConfidenceInterval {
    pub lower: f64,
    pub upper: f64,
    pub level: f64,
}

Confidence interval for match score.

Provides uncertainty bounds around the match score, useful for understanding match reliability.

Fields

lower: f64

Lower bound of confidence (0.0 - 1.0)

upper: f64

Upper bound of confidence (0.0 - 1.0)

level: f64

Confidence level (e.g., 0.95 for 95% CI)

Implementations

impl ConfidenceInterval

pub const fn new(lower: f64, upper: f64, level: f64) -> Self

Create a new confidence interval.

pub fn from_score_and_error(score: f64, std_error: f64) -> Self

Create a 95% confidence interval from a score and standard error.

Uses ±1.96 × SE for 95% CI.

pub fn from_tier(score: f64, tier: &str) -> Self

Create a simple confidence interval based on the matching tier.

Exact matches have tight intervals, fuzzy matches have wider intervals.

pub fn width(&self) -> f64

Get the width of the interval.
