Rust Axum Middleware - Extract Version from Header

Custom extractor for Rust Axum to extract the version from an HTTP header X-Version. Works ONLY with Rust Axum.

Usage

use axum::{routing::get, Router};
use version_middleware::ExtractVersion;

async fn handler(ExtractVersion(version): ExtractVersion) {
    println!("Version: {:?}", version);
}

let app = Router::<()>::new().route("/foo", get(handler));

The extracted value is :

• trim to clean extra spaces, before and after ;
• lowercase to standardize and make it more resilient to implementation errors.

Samples

Extract version if the header is explicitly set

curl -H "X-Version: v1.0.0" http://api.nebeto.xyz/foo
curl -H "x-version: preView" http://api.nebeto.xyz/foo
curl -H "X-VeRSion: latest" http://api.nebeto.xyz/foo

Will give respectively v1.0.0, preview and latest.

Extract version if the header is missing

curl http://api.nebeto.xyz/foo

Will give by default latest.
