Struct LanguageDetector 

pub struct LanguageDetector;

Language detection utilities

Provides methods for detecting programming languages from file paths, file content, or both.

Implementations

impl LanguageDetector

pub fn from_extension(path: &Path) -> Language

Detect language from file extension

Arguments

• path - Path to the file

Returns

The detected language, or Language::Unknown if extension is not recognized

Example

let lang = LanguageDetector::from_extension(Path::new("main.rs"));
assert_eq!(lang, Language::Rust);

pub fn from_content(content: &str) -> Language

Detect language from file content (shebang or imports)

Arguments

• content - The file content to analyze

Returns

The detected language based on content patterns, or Language::Unknown

Example

let lang = LanguageDetector::from_content("#!/usr/bin/env python\nprint('hello')");
assert_eq!(lang, Language::Python);

pub fn detect(path: &Path, content: &str) -> Language

Detect language from both extension and content

Arguments

• path - Path to the file
• content - The file content to analyze

Returns

The detected language, preferring extension detection over content detection

Example

let lang = LanguageDetector::detect(
    Path::new("main.rs"),
    "fn main() {}"
);
assert_eq!(lang, Language::Rust);
