Macro register_persisted_value 

macro_rules! register_persisted_value {
    ($(#[$meta:meta])* $vis:vis $name:ident: $ty:ty = $key:literal) => { ... };
}

Register a type-safe persisted value key.

This macro is the primary way to create persisted value keys. It associates a string key name with a value type at compile time.

Important: The key name must be globally unique across the entire application. Using the same key name for different persisted values will cause conflicts. It may contain only ASCII letters and underscores, which is checked at compile time.

Example

use bitwarden_state::register_persisted_value;
use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize)]
struct AppConfig {
    theme: String,
    auto_save: bool,
}

register_persisted_value!(CONFIG: AppConfig = "app_config");
