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

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Pattern

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Pattern

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for Pattern

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
