bevy_pkv

Bevy pkv is a persistent key value store for bevy.

The end goal is to write something cross-platform (including web) that allows storing things like settings, save games etc. It should just be a thin wrapper around other crates.

It's currently using sled + bincode for storage, I'm not sure if that's the best choice, but it will do for now.

It currently creates a single global key value store when the plugin is initialized.

Usage

Add the plugin to your app

rust App::new() .add_plugins(DefaultPlugins) .add_plugin(PkvPlugin) .run();

Use it in a system:

```rust fn setup(mut pkv: ResMut) { if let Ok(username) = pkv.get::("username") { info!("Welcome back {username}"); } else { pkv.set_string("username", "alice") .expect("failed to store username");

    // alternatively, using the slightly less efficient generic api:
    pkv.set("username", &"alice".to_string())
        .expect("failed to store username");
}

} ```

Using your own types implementing serde::Serialize and Deserialize:

```rust

[derive(Serialize, Deserialize)]

struct User { name: String, }

fn setup(mut pkv: ResMut) { if let Ok(user) = pkv.get::("user") { info!("Welcome back {}", user.name); } else { let user = User { name: "bob".to_string(), }; pkv.set("user", &user).expect("failed to store username"); } } ```

See the examples for further usage

Bevy version support

The main branch targets the latest bevy release.

I intend to support the main branch of Bevy in the bevy-main branch.
