Get the latest version for your Cargo.toml from crates.io.

Serde

HttpApiProblem implements Serialize and Deserialize.

Examples

use http_api_problem::*;

let p = HttpApiProblem::with_title_and_type_from_status(HttpStatusCode::NotFound)
    .set_detail("detailed explanation")
    .set_instance("/on/1234/do/something");

assert_eq!(Some("https://httpstatuses.com/404".to_string()), p.type_url);
assert_eq!(Some(HttpStatusCode::NotFound), p.status);
assert_eq!("Not Found".to_string(), p.title);
assert_eq!(Some("detailed explanation".to_string()), p.detail);
assert_eq!(Some("/on/1234/do/something".to_string()), p.instance);

There is also From<u16> implemented for HttpStatusCode:

use http_api_problem::*;

let p = HttpApiProblem::with_title_and_type_from_status(428)
    .set_detail("detailed explanation")
    .set_instance("/on/1234/do/something");

assert_eq!(Some("https://httpstatuses.com/428".to_string()), p.type_url);
assert_eq!(Some(HttpStatusCode::PreconditionRequired), p.status);
assert_eq!("Precondition Required".to_string(), p.title);
assert_eq!(Some("detailed explanation".to_string()), p.detail);
assert_eq!(Some("/on/1234/do/something".to_string()), p.instance);

Features

Web Frameworks

There are multiple features to integrate with web frameworks:

• with-warp
• with-hyper
• with-actix-web

These mainly convert the HttpApiProblem to response types of the frameworks and implement traits to integrate with the frameworks error handling

ApiError

The feature with-api-error enables a structure which can be return from "api handlers" that generate responses and can be converted into an HttpApiProblem.
