Sessioning middleware for the Iron web framework.
// 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());

fn id_generator(req: &Request) -> id_type { ... }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
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.
Along with the online documentation,
you can build a local copy with cargo doc.
