Example:

use actix_web::{web, App};
use serde::Deserialize;
use actix_web_validator::Query;
use validator::Validate;

#[derive(Debug, Deserialize)]
pub enum ResponseType {
    Token,
    Code
}

#[derive(Deserialize, Validate)]
pub struct AuthRequest {
    #[validate(range(min = 1000, max = 9999))]
    id: u64,
    response_type: ResponseType,
}

// Use `Query` extractor for query information (and destructure it within the signature).
// This handler gets called only if the request's query string contains a `id` and
// `response_type` fields.
// The correct request for this handler would be `/index.html?id=1234&response_type=Code"`.
async fn index(info: Query<AuthRequest>) -> String {
    format!("Authorization request for client with id={} and type={:?}!", info.id, info.response_type)
}

fn main() {
    let app = App::new().service(
        web::resource("/index.html").route(web::get().to(index))); // <- use `Query` extractor
}
