persistent

Persistent storage as middleware for the Iron web framework.

Example

```rust use iron::Plugin; // Request::get is provided through this trait.

pub struct HitCounter; impl Assoc for HitCounter {}

fn serve_hits(req: &mut Request) -> IronResult { let mutex = req.get::>().unwrap(); let mut count = mutex.lock();

*count += 1;
Ok(Response::with(status::Ok, format!("Hits: {}", *count)))

}

fn main() { let mut chain = ChainBuilder::new(serve_hits); chain.link(Write::::both(0u)); Iron::new(chain).listen(Ipv4Addr(127, 0, 0, 1), 3000); } ```

Overview

persistent is a part of Iron's core bundle.

• Share persistent data across requests
• Read or modify locally stored data

Installation

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

```toml [dependencies.persistent]

git = "https://github.com/iron/persistent.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 make doc.
