pub struct LanguageDetector { /* private fields */ }

Runtime language detector with optional custom pattern rules.

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

Panics

Implementations

impl LanguageDetector

pub fn new() -> Self

Creates a detector with built-in default patterns.

Examples

use http_handle::language::{Language, LanguageDetector};
let detector = LanguageDetector::new();
assert_eq!(detector.detect("def f(): pass"), Language::Python);

Panics

This function panics only if a built-in regex literal is invalid.

pub fn with_custom_pattern( self, language: Language, pattern: &str, ) -> Result<Self, Error>

Adds a runtime custom pattern to detect a specific language.

Examples

use http_handle::language::{Language, LanguageDetector};
let detector = LanguageDetector::new()
    .with_custom_pattern(Language::Go, r"\\bpackage\\b")
    .expect("valid regex");
assert_eq!(detector.detect("package main"), Language::Go);

Errors

Returns an error when pattern is not a valid regular expression.

Panics

This function does not panic.

pub fn detect(&self, input: &str) -> Language

Detects the first matching language for a text.

Examples

use http_handle::language::{Language, LanguageDetector};
let detector = LanguageDetector::new();
assert_eq!(detector.detect("const x = 1;"), Language::JavaScript);

Panics

This function does not panic.
