Function put 

pub fn put<St: State, U: 'static>() -> Route<St, U>

Create route with PUT method guard.

use ntex::web;

let app = web::App::default().service(
    web::resource("/{project_id}")
        .route(web::put().to(async || { web::HttpResponse::Ok() }))
);

In the above example, one PUT route gets added:

• /{project_id}
