[][src]Struct actix_web::middleware::errhandlers::ErrorHandlers

pub struct ErrorHandlers<B> { /* fields omitted */ }

Middleware for allowing custom handlers for responses.

You can use ErrorHandlers::handler() method to register a custom error handler for specific status code. You can modify existing response or create completely new one.


use actix_web::middleware::errhandlers::{ErrorHandlers, ErrorHandlerResponse};
use actix_web::{web, http, dev, App, HttpRequest, HttpResponse, Result};

fn render_500<B>(mut res: dev::ServiceResponse<B>) -> Result<ErrorHandlerResponse<B>> {
       .insert(http::header::CONTENT_TYPE, http::HeaderValue::from_static("Error"));

let app = App::new()
            .handler(http::StatusCode::INTERNAL_SERVER_ERROR, render_500),
        .route(web::get().to(|| HttpResponse::Ok()))
        .route(web::head().to(|| HttpResponse::MethodNotAllowed())


impl<B> ErrorHandlers<B>[src]

pub fn new() -> Self[src]

Construct new ErrorHandlers instance

pub fn handler<F>(self, status: StatusCode, handler: F) -> Self where
    F: Fn(ServiceResponse<B>) -> Result<ErrorHandlerResponse<B>> + 'static, 

Register error handler for specified status code
