A URL expansion engine that supports an extensive registry of shortening services. It combines fast domain detection with robust resolution strategies: HTTP redirect following, pattern-based extraction from intermediate HTML, and API-based expansion for shorteners that don’t emit standard 3xx redirects. Returns the canonical final URL with consistent error handling and configurable timeouts.

This module recognizes hundreds of popular URL shorteners and expands them to their true destination

• async

urlexpand = "0.3.0"

and then

use std::time::Duration;
use urlexpand::unshorten;

fn main() {
    let url = "https://bit.ly/3alqLKi";
    assert!(unshorten(url, Some(Duration::from_secs(10))).await.is_ok());   // with timeout
    assert!(unshorten(url, None).await.is_ok());    // without timeout
}

• blocking

urlexpand = { version = "0.3.0", features = ["blocking"] }

and then

use std::time::Duration;
use urlexpand::unshorten;

fn main() {
    let url = "https://bit.ly/3alqLKi";
    assert!(unshorten(url, Some(Duration::from_secs(10))).is_ok());   // with timeout
    assert!(unshorten(url, None).is_ok());    // without timeout
}

cargo run --example unshorten https://bit.ly/3alqLKi
