Macro vpath

macro_rules! vpath {
    ($e:expr) => { ... };
}

This macro aborts compilation if the path is invalid.

This example will fail to compile:

use axum::routing::{Router, get};
use axum_extra::vpath;

let router = axum::Router::<()>::new()
    .route(vpath!("invalid_path"), get(root))
    .to_owned();

async fn root() {}

This one will compile without problems:

use axum::routing::{Router, get};
use axum_extra::vpath;

let router = axum::Router::<()>::new()
    .route(vpath!("/valid_path"), get(root))
    .to_owned();

async fn root() {}

This macro is available only on rust versions 1.80 and above.
