Rocket

Rocket is a work-in-progress web framework for Rust (nightly) with a focus on ease-of-use, expressability, and speed. It currently does not work. But, when it does, the following will be the canonical "Hello, world!" example:

#![feature(plugin)]
#![plugin(rocket_macros)]

extern crate rocket;
use rocket::Rocket;

#[route(GET, path = "/hello/<name>/<age>")]
fn hello(name: &str, age: i8) -> String {
    format!("Hello, {} year old named {}!", age, name)
}

fn main() {
    let mut rocket = Rocket::new("localhost", 8000);
    rocket.mount_and_launch("/", routes![hello]);
}

Rocket requires a nightly version of Rust as it makes heavy use of syntax extensions. This also means that the first two unwieldly lines in the Rust file above are required.

Building

Try running the examples in the examples/ folder. For instance, the following sequence of commands builds the Hello, world! example:

cd examples/hello
cargo build
cargo run

Then visit localhost:8000/hello/{some_name}, replacing {some_name} with some name.

OS X

Apple has stopped shipping openssl with OS X.11. As such, if your build fails compile, you'll need to install openssl, cargo clean, and then cargo build again. Here are some lightweight instructions:

brew install openssl
brew link --force openssl
export OPENSSL_INCLUDE_DIR=`brew --prefix openssl`/include
export OPENSSL_LIB_DIR=`brew --prefix openssl`/lib
