pub struct Compat<T> { /* private fields */ }
Expand description

Middleware for enabling any middleware to be used in Resource::wrap, and Condition.

Examples

use actix_web::middleware::{Logger, Compat};
use actix_web::{App, web};

let logger = Logger::default();

// this would not compile because of incompatible body types
// let app = App::new()
//     .service(web::scope("scoped").wrap(logger));

// by using this middleware we can use the logger on a scope
let app = App::new()
    .service(web::scope("scoped").wrap(Compat::new(logger)));
