session

Sessioning middleware for the Iron web framework.

Example

// Echo the sessioned count to the client
fn get_count(req: &mut Request, res: &mut Response) -> IronResult<()> {
    // Retrieve our session from the store
    let session = req.extensions.find_mut::<Session<SocketAddr, u32>>().unwrap();
    // Store or increase the sessioned count
    let count = session.upsert(1u32, |v: &mut u32| { *v = *v + 1; } );

    println!("{} hits from\t{}", count, req.remote_addr.unwrap())
    let _ = res.serve(::http::status::Ok, format!("Sessioned count: {}", count).as_slice());

    Continue
}

fn main() {
    let mut server: Iron = Iron::new();
    server.chain.link(Sessions::new(id_from_socket_addr, HashSessionStore::<id_type, u32>::new()));
    server.chain.link(Chain::new(get_count));
    server.listen(Ipv4Addr(127, 0, 0, 1), 3000);
}

fn id_generator(req: &Request) -> id_type { ... }

Overview

session is a part of Iron's core bundle.

• Includes an implemented HashMap-based session store
• Key sessions based on your own id generating function
• Store and retrieve data to/from keyed sessions

Installation

If you're using a Cargo.toml to manage dependencies, just add session to the toml:

[dependencies.session]

git = "https://github.com/iron/session.git"

Otherwise, cargo build, and the rlib will be in your target directory.

Documentation

Along with the online documentation, you can build a local copy with cargo doc.
