# HTTP-API-PROBLEM

A library to create HTTP response content for APIs based on RFC7807.

## Usage

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

Add this to your crate root:

rust extern crate http_api_problem;

## serde

HttpApiProblem implements Serialize and Deserialize for HttpApiProblem.

## Examples

```rust use httpapiproblem::*;

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

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

There is also From<u16> implemented for HttpStatusCode:

```rust use httpapiproblem::*;

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

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

## Features

### with_iron

There is a conversion between irons StatusCode and HttpStatusCode back and forth.

The HttpApiProblem provides a method to_iron_response which constructs an iron Response. If the status field of the HttpApiProblem is None 500 - Internal Server Error is the default.

From<HttpApiProblem for iron::response::Response will also be there. It simply calls to_iron_response.

Additionally there will be a function into_iron_response which converts anything into an iron::response::Response that can be converted into a HttpApiProblem.

### with_hyper

There is a conversion between hyperss StatusCode and HttpStatusCode back and forth.

The HttpApiProblem provides a method to_hyper_response which constructs an hyper Response. If the status field of the HttpApiProblem is None 500 - Internal Server Error is the default.

From<HttpApiProblem for hyper::Response will also be there. It simply calls to_hyper_response.

Additionally there will be a function into_hyper_response which converts anything into a hyper::Response that can be converted into a HttpApiProblem.

### with_rocket(nightly only)

There is a conversion between rockets Status and HttpStatusCode back and forth.

HttpApiProblem implements rocket::response::Responder, allowing it to be returned from rocket handlers directly (e.g. as Result<T, HttpApiProblem>). It also provides a method to_rocket_response which explicitly constructs a rocket Response. If the status field of the HttpApiProblem is None 500 - Internal Server Error is the default.

From<HttpApiProblem for rocket::Response will also be there. It simply calls to_rocket_response.

Additionally there will be a function into_rocket_response which converts anything into a rocket::Response that can be converted into a HttpApiProblem.
