Struct Pattern 

pub struct Pattern {
    pub name: String,
    pub regex: String,
    pub match_count: usize,
    pub match_percentage: f64,
    pub category: PatternCategory,
    pub confidence: f64,
}

A detected value pattern within a column (e.g. email, phone, UUID).

Fields

name: String

Pattern name (e.g. “Email”, “Phone (US)”, “UUID”)

regex: String

Regex used for detection

match_count: usize

Number of values matching this pattern

match_percentage: f64

Percentage of non-null values matching (0.0–100.0)

category: PatternCategory

Semantic category (e.g. contact, network, financial)

confidence: f64

Detection confidence score (0.0–1.0), derived from pattern specificity and match rate
