# Actix Sled Session
_An Actix Web Session Backend using the Sled embedded database_

- [Join the discussion on Matrix](https://matrix.to/#/!BMSjFeYeYeDoxQxpUr:asonix.dog?via=asonix.dog)

This session backend sets an cookie with a unique ID for each incoming request that doesn't
already have an ID set, and uses that ID as a key to look up session data from a Sled tree.

### Usage
#### Update your Cargo.toml
```toml
[dependencies]
actix = "0.8"
actix-sled-session = "0.2"
actix-web = "1.0"
```

#### Use it in your project
```rust
use actix::System;
use actix_web::{web, App, HttpServer};
use actix_sled_session::{Session, SledSession};

fn index(session: Session) -> String {
    if let Ok(Some(item)) = session.get::<usize>("item") {
        println!("item, {}", item);
        session.clear();
        return format!("Got item, {}", item);
    }

    let _ = session.set::<usize>("item", 3);
    String::from("Set item!")
}

fn main() -> Result<(), failure::Error> {
    let sys = System::new("example");
    let session_backend = SledSession::new_default()?;

    HttpServer::new(move || {
        App::new()
            .wrap(session_backend.clone())
            .route("/", web::get().to(index))
    })
        .bind("127.0.0.1:9876")?
        .start();

    sys.run()?;
    Ok(())
}
```
