# Hyper Router [![Build Status](https://travis-ci.com/marad/hyper-router.svg?branch=master)](https://travis-ci.com/marad/hyper-router)
This cargo is a small extension to the great Hyper HTTP library. It basically is
adds the ability to define routes to request handlers and then query for the handlers
by request path.
[API Documentation](https://docs.rs/hyper-router/latest/hyper_router/)
## Usage
To use the library just add:
```
hyper = "^0.12"
hyper-router = "^0.5"
```
to your dependencies.
```rust
extern crate hyper;
extern crate hyper_router;
use hyper::header::{CONTENT_LENGTH, CONTENT_TYPE};
use hyper::{Request, Response, Body, Method};
use hyper::server::Server;
use hyper::rt::Future;
use hyper_router::{Route, RouterBuilder, RouterService};
fn request_handler(_: Request
) -> Response {
let body = "Hello World";
Response::builder()
.header(CONTENT_LENGTH, body.len() as u64)
.header(CONTENT_TYPE, "text/plain")
.body(Body::from(body))
.expect("Failed to construct the response")
}
fn router_service() -> Result {
let router = RouterBuilder::new()
.add(Route::get("/greet").using(request_handler))
.build();
Ok(RouterService::new(router))
}
fn main() {
let addr = "0.0.0.0:8080".parse().unwrap();
let server = Server::bind(&addr)
.serve(router_service)
.map_err(|e| eprintln!("server error: {}", e));
hyper::rt::run(server)
}
```
This code will start Hyper server and add use router to find handlers for request.
We create the `Route` so that when we visit path `/greet` the `basic_handler` handler
will be called.
## Things to note
* you can specify paths as regular expressions so you can match every path you please.
* If you have request matching multiple paths the one that was first `add`ed will be chosen.
* ~~This library is in an early stage of development so there may be breaking changes comming.~~ -
it seems that the library is quite popular so I'm not going to do compatibility breaking changes.
# Further Development
* add the ability to distinguish requests by query parameters.
# Waiting for your feedback
I've created this little tool to help myself learn Rust and to avoid using big frameworks
like Iron or rustful. I just want to keep things simple.
Obviously I could make some errors or bad design choices so I'm waiting for your feedback!
