ferrite

=======

A typesafe API wrapper generator for Rust, in the same vein as Retrofit for Java (https://square.github.io/retrofit/).

Compared to Retrofit, ferrite generates the glue-code at compile-time; no runtime reflection necessary. Generated functions return informative errors on failure, and can be called just like any other Rust function.

Currently only a proof-of-concept, ferrite needs quite a bit more work to reach feature-parity with Retrofit,

and even the underlying [`rest_client`](https://github.com/gtolle/rest_client) library that powers it.

* ~~POST Requests~~

* Miscellaneous REST verbs (PUT, DELETE, HEAD, etc.) (Easily implemented)

* ~~URL Interpolation (e.g. replacing `{id}` in `/users/{id}/posts/` with a dynamic argument)~~

* Multipart/file/binary uploads (using `Reader`)

* Generation of methods (e.g. functions in an `impl` that take `&self`) that can pass struct fields as parameters

* Support for generics (necessary?)

* Configurable parameter keys (necessary?)

* Static/dynamic manipulation of headers (necessary?)

* Usability/readability tweaks to syntax

Usage

-----

Add to your `Cargo.toml`:

```

[dependencies.ferrite]

git = "https://github.com/cybergeek94/ferrite"

```

```rust

extern crate ferrite; // Not sure if needs #[phase(plugin)]

// Ferrite's error type needs to be in-scope for the function signatures

use self::ferrite::APIError; 

    

#[deriving(Decodable)]

struct Test {

    hello: String,

}

    

// Function will have the following generated signature:

// fn hello_world() -> Result (this is why the error type needs to be in-scope)

get!("https://raw.githubusercontent.com/cybergeek94/ferrite/master/json/hello_world.json":

    fn hello_world() -> Test)

  

// Vectors are automatically decoded!

get!("https://raw.githubusercontent.com/cybergeek94/ferrite/master/json/hello_vec.json": 

    fn hello_vec() -> Vec)

   

// Wrap URL format parameters with {} 

get!("https://raw.githubusercontent.com/cybergeek94/ferrite/master/json/hello_{}.json": 

    fn hello{val: &str}() -> Test)

// POST requests now available!

post!("https://raw.githubusercontent.com/cybergeek94/ferrite/master/json/hello_world.json":

        fn post_hello_world() -> Test)

fn main() {

    let test = hello_world().unwrap();

    assert!(test.hello.as_slice() == "world");

    

    let test = hello("world").unwrap();

    assert!(test.hello.as_slice() == "world"); 

    

    let test_vec = hello_vec().unwrap();

    let mut test_iter = test_vec.iter();

    assert!(test_iter.next().unwrap().hello.as_slice() == "world");

    assert!(test_iter.next().unwrap().hello.as_slice() == "nation");

    assert!(test_iter.next().unwrap().hello.as_slice() == "city");

    assert!(test_iter.next().unwrap().hello.as_slice() == "person");

    assert!(test_iter.next().is_none());

    let test = post_hello_world().unwrap();

    assert!(test.hello.as_slice() == "world");

}
