A few important things needs to get this to be 'right': 1a. Have a way to return a response with a status code. 1b. Use that mechanism in the default catchers. 2. Automatically fill in that code from the #[error] handler. 3. Have a way for a responder to say if responding succeeded. 4. Try next highest ranking route if responding with one handler fails. |

Rocket
Rocket is a work-in-progress web framework for Rust (nightly) with a focus on ease-of-use, expressability, and speed. Here's an example of a complete Rocket application:
#![feature(plugin)]
#![plugin(rocket_macros)]
extern crate rocket;
use rocket::Rocket;
#[route(GET, path = "/<name>/<age>")]
fn hello(name: &str, age: u8) -> String {
format!("Hello, {} year old named {}!", age, name)
}
fn main() {
Rocket::new("localhost", 8000).mount_and_launch("/hello", routes![hello]);
}
Visiting localhost:8000/hello/John/58, for example, will trigger the hello
route resulting in the string Hello, 58 year old named John! being sent to the
browser. If an <age> string was passed in that can't be parsed as a u8, the
route won't get called, resulting in a 404 error.
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 and runs the Hello, world! example:
cd examples/hello_world
cargo run
Then visit localhost:8000. You should see Hello, world!.
OS X
Apple has stopped shipping openssl with OS X.11. As such, if your build fails
to compile with some openssl related errors, 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
