pub struct QueryConfig {
    pub ehandler: Option<Arc<dyn Fn(Error, &HttpRequest) -> Error + Send + Sync>>,
}

Query extractor configuration.

Example

use actix_web::{error, web, App, FromRequest, HttpResponse};
use serde::Deserialize;
use actix_web_validator::{Query, QueryConfig};
use validator::Validate;

#[derive(Deserialize, Validate)]
struct Info {
    #[validate(length(min = 1))]
    username: String,
}

/// deserialize `Info` from request's querystring
async fn index(info: Query<Info>) -> String {
    format!("Welcome {}!", info.username)
}

fn main() {
    let query_config = QueryConfig::default()
        .error_handler(|err, req| {  // <- create custom error response
            error::InternalError::from_response(err, HttpResponse::Conflict().finish()).into()
        });
    let app = App::new().service(
        web::resource("/index.html")
            .app_data(query_config)
            .route(web::post().to(index))
    );
