Struct StatePersistence 

pub struct StatePersistence;

Provides utility methods for loading and saving AppState from/to disk.

Implementations

impl StatePersistence

pub fn get_state_path(config: &AppConfig) -> PathType

Derives the default save path for the application state using /opt/artisan/tmp/.<app_name>.state.

Example

let config = AppConfig::dummy();
let path = StatePersistence::get_state_path(&config);
println!("State file path: {:?}", path);

pub async fn save_state( state: &AppState, path: &PathType, ) -> Result<(), Box<dyn Error>>

Saves the provided AppState to the specified path.
The data is serialized to TOML, then encrypted with simple_encrypt.

Errors

• Returns an Err if serialization, encryption, or writing to the file fails.

pub async fn load_state(path: &PathType) -> Result<AppState, Box<dyn Error>>

Loads an AppState from the specified path.
Reads the file, then decrypts it with simple_decrypt, and finally deserializes from TOML.

Errors

• Returns an Err if decryption or TOML deserialization fails, or if the file is unreadable.
