Struct actix_web::middleware::DefaultHeaders

pub struct DefaultHeaders { /* fields omitted */ }

Middleware for setting default response headers.

use actix_web::*;

fn main() {
    let app = Application::new()
        .middleware(
            middleware::DefaultHeaders::build()
                .header("X-Version", "0.2")
                .finish())
        .resource("/test", |r| {
             r.method(Method::GET).f(|_| httpcodes::HttpOk);
             r.method(Method::HEAD).f(|_| httpcodes::HttpMethodNotAllowed);
        })
        .finish();
