Struct LanguageDetector 

pub struct LanguageDetector { /* private fields */ }

Detector for identifying language codes from filesystem paths.

Implementations

impl LanguageDetector

pub fn new() -> Self

Create a new LanguageDetector with default language mappings and patterns.

Initializes internal dictionaries and regex patterns for detection. Do not translate these language codes to English rustdoc!!!

pub fn detect_from_path(&self, path: &Path) -> Option<LanguageInfo>

Detect a single language information from the given path.

Behavior

Attempts detection by directory name first, then by filename pattern.

pub fn normalize(&self, raw: &str) -> Option<String>

Normalize a raw language label (typically supplied by an AI model) into the project’s canonical short code.

Behavior

• The input is lower-cased before lookup.
• Known synonyms are collapsed via the internal language_codes map (e.g. "english"/"eng"/"EN" → "en", "cht"/"繁中"/"traditional-chinese" is matched against the same map; for the latter, only entries the detector knows are mapped).
• Unknown but otherwise valid [A-Za-z0-9_-]{1,16} tokens are passed through verbatim after lower-casing.
• Returns None for empty input.

Arguments

• raw - The raw language label to normalize.

Returns

Some(code) with the canonical or pass-through code, or None when the input is empty.

pub fn get_primary_language(&self, path: &Path) -> Option<String>

Return the primary detected language code for the provided path.

Returns

Some(code) if detected, otherwise None.

pub fn detect_all_languages(&self, path: &Path) -> Vec<LanguageInfo>

Collect all potential language detections from the path.

Sorts results by confidence and removes duplicates by code.

Trait Implementations

impl Default for LanguageDetector

fn default() -> Self

Returns the “default value” for a type.
