Accessing from Rust

When the ManagerExt trait is in scope, you can access your stores from any type that implements the Manager trait (e.g. AppHandle, Window, WebviewWindow).

Note that all values are stored as serde_json::Value, so you may need to convert them to the desired type when accessing from Rust. You can check the serde_json documentation for more information.

A list of all available methods for the stores can be found here.

use tauri_plugin_zustand::ManagerExt;

#[tauri::command]
fn get_counter(app: AppHandle) -> i32 {
  let value = app
    .zustand()
    .get("store", "counter")
    .unwrap();

  serde_json::from_value(value).unwrap()
}

You can also use the try_get method to get the value directly as the desired type.

use tauri_plugin_zustand::ManagerExt;

#[tauri::command]
fn try_get_counter(app: AppHandle) -> i32 {
  app
    .zustand()
    .try_get::<i32>("store", "counter")
    .unwrap()
}

Watching for changes

The watch method can be used to set up a closure that will be called whenever the state of the store changes.

use tauri_plugin_zustand::ManagerExt;

#[tauri::command]
fn watch_store(app: AppHandle) {
  app.zustand().watch("store", |app| {
    let counter = app
      .zustand()
      .try_get::<i32>("store", "counter")?;

    println!("counter: {counter}");

    Ok(())
  });
}
