Enum Recognizer 

pub enum Recognizer {
    Integer {
        near: Vec<String>,
    },
    Money,
    Regex(Regex),
    OneOf(Vec<String>),
    Fuzzy {
        options: Vec<String>,
        min: f64,
    },
    YesNo,
    DateTime,
}

A deterministic transcript recognizer: text -> (value, confidence).

Recognizers run on the CPU over the user transcript. Confidence is in 0.0..=1.0; deterministic matches are high-confidence, fuzzy matches carry their similarity score.

Variants

Integer

First integer in the text. If near is non-empty, at least one anchor word must be present for the match to count.

Fields

near: Vec<String>

Anchor words that must appear for the integer to be recognized.

Money

A monetary amount ($1,250.00, 200) → JSON number.

Regex(Regex)

First capture group (or whole match) of a regex → string.

OneOf(Vec<String>)

The first option that appears (case-insensitive substring) → string.

Fuzzy

The option with the best Jaro-Winkler similarity ≥ min → string. Useful for ASR-mangled names matched against a roster.

Fields

options: Vec<String>

Candidate values to match against.

min: f64

Minimum similarity in 0.0..=1.0.

YesNo

Affirmative/negative detection → boolean.

DateTime

A calendar/clock expression → a JSON object with any of the keys date (YYYY-MM-DD), time (24h HH:MM), day (today/tomorrow/ tonight/yesterday), weekday, and part (morning/afternoon/ evening/noon/midnight). Deterministic, on-device — a small Duckling-style normalizer, not a full grammar.

Implementations

impl Recognizer

pub fn integer() -> Recognizer

First integer, optionally anchored to nearby words.

pub fn integer_near<I, S>(anchors: I) -> Recognizer

where I: IntoIterator<Item = S>, S: Into<String>,

Integer recognized only when one of anchors is present.

pub fn money() -> Recognizer

A monetary amount.

pub fn regex(pattern: &str) -> Recognizer

A regex (first capture group, or the whole match).

pub fn one_of<I, S>(options: I) -> Recognizer

where I: IntoIterator<Item = S>, S: Into<String>,

Match against a fixed set of options (case-insensitive substring).

pub fn fuzzy<I, S>(options: I) -> Recognizer

where I: IntoIterator<Item = S>, S: Into<String>,

Fuzzy-match against options with a default 0.85 threshold.

pub fn yes_no() -> Recognizer

Affirmative/negative.

pub fn datetime() -> Recognizer

A calendar/clock expression normalized to a JSON object.

pub fn recognize(&self, text: &str) -> Option<(Value, f32)>

Recognize a value in text, with a confidence in 0.0..=1.0.

Trait Implementations

impl Clone for Recognizer

fn clone(&self) -> Recognizer

Returns a duplicate of the value.

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

Performs copy-assignment from source.
