pub struct PermissionGuard<Type> { /* private fields */ }

Implementation of Guard trait for validate permissions

use actix_web::dev::ServiceRequest;
use actix_web::{web, App, Error, HttpResponse, HttpServer};

use actix_web_grants::{GrantsMiddleware, PermissionGuard};
use std::sync::Arc;

fn main() {
    HttpServer::new(|| {
        App::new()
            .wrap(GrantsMiddleware::with_extractor(extract))
            .service(web::resource("/admin")
                    .to(|| async { HttpResponse::Ok().finish() })
                    .guard(PermissionGuard::new("ROLE_ADMIN".to_string())))
    });
}

async fn extract(_req: &ServiceRequest) -> Result<Vec<String>, Error> {
   // Here is a place for your code to get user permissions/grants/permissions from a request
   // For example from a token or database

   // Stub example
   Ok(vec!["ROLE_ADMIN".to_string()])
}
