Struct Pattern 

pub struct Pattern {
    pub pattern: String,
    pub grapheme_len: usize,
    pub custom_unique_id: Option<usize>,
    pub weight: f32,
    pub limits: Option<FuzzyLimits>,
}

A search pattern with optional weight and fuzzy limits.

Patterns can be created from strings or tuples for convenience.

Fields

pattern: String

The pattern string.

grapheme_len: usize

Length in grapheme clusters.

custom_unique_id: Option<usize>

Optional custom ID for uniqueness tracking.

weight: f32

Pattern weight (default 1.0).

limits: Option<FuzzyLimits>

Per-pattern fuzzy limits.

Implementations

impl Pattern

pub fn as_str(&self) -> &str

Get the pattern as a string slice.

pub fn len(&self) -> usize

Get the byte length of the pattern.

pub fn is_empty(&self) -> bool

Check if the pattern is empty.

pub fn weight(self, weight: f32) -> Self

Set pattern weight.

pub fn fuzzy(self, limits: FuzzyLimits) -> Self

Set per-pattern fuzzy limits.

pub fn custom_unique_id(self, id: usize) -> Self

Set custom unique ID for pattern deduplication.

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 From<&String> for Pattern

fn from(s: &String) -> Self

Converts to this type from the input type.

impl From<&str> for Pattern

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<(&String, f32)> for Pattern

fn from((s, w): (&String, f32)) -> Self

Converts to this type from the input type.

impl From<(&str, f32)> for Pattern

fn from((s, w): (&str, f32)) -> Self

Converts to this type from the input type.

impl From<(&str, f32, u8)> for Pattern

fn from((s, w, max_edits): (&str, f32, NumEdits)) -> Self

Converts to this type from the input type.

impl From<(String, f32)> for Pattern

fn from((s, w): (String, f32)) -> Self

Converts to this type from the input type.

impl From<(String, f32, u8)> for Pattern

fn from((s, w, max_edits): (String, f32, NumEdits)) -> Self

Converts to this type from the input type.

impl From<String> for Pattern

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for Pattern

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