This simple crate allows you to remap actix-web errors to your own custom error type. You could for example return a html wrapped error.
Your custom error trait has to implement the
std::convert::From<actix_web::Error> and the actix_web::ResponseError traits.
```rust use actixerrormappermiddleware::MapperService; use actixjwtauthmiddleware::{AuthService, Authority}; use actixweb::{web, App, Error as ActixError, HttpResponse, HttpServer, ResponseError}; use rustyhtml::{html, HTMLify};
async fn main() -> std::io::Result<()> {
HttpServer::new(move || {
App::new()
// this wrap will catch every error thrown in the Apps scope an convert it to the MyError type
.wrap(MapperService::
struct MyError { error: ActixError, }
impl std::convert::From
impl std::fmt::Display for MyError { fn fmt(&self, f: &mut std::fmt::Formatter<'>) -> std::fmt::Result { f.writefmt(formatargs!( "An error occurred: \"{}\"", self.error.tostring() )) } }
impl ResponseError for MyError { fn statuscode(&self) -> actixweb::http::StatusCode { self.error.asresponseerror().status_code() }
fn error_response(&self) -> actix_web::HttpResponse<actix_web::body::BoxBody> {
HttpResponse::build(self.status_code()).body(html!(
<html style="
margin: 0;
height: 100%;
">
<head>
<title>Error</title>
</head>
<body style="
display: grid;
margin: 0;
height: 100%;
width: 100%;
font-family: 'Raleway';
place-items: center;
color: #fff;
overflow-y: hidden;
background: #000;
">
<section style="
padding: 2rem;
background: #289dcc;
">
<h1>Ups . . .</h1>
<p>{self.to_string()}</p>
</section>
</body>
</html>
))
}
} ```
