Struct SavedDataManager 

pub struct SavedDataManager {
    data_dir: Option<PathBuf>,
}

Typed saved-data storage for a loaded world.

Fields

data_dir: Option<PathBuf>

Implementations

impl SavedDataManager

pub fn new(world_dir: Option<&Path>) -> Self

Creates saved-data storage rooted at world_dir/data.

None means the world is ephemeral, matching Steel’s RAM-only storage.

pub fn sync_load_wincode<T>( &self, name: WincodeSavedDataName, ) -> Result<Option<T>>

where for<'de> T: SchemaRead<'de, DefaultConfig, Dst = T>,

Loads a versioned wincode value, or returns None when it is absent or this world has no persistent storage.

pub async fn load_or_default<T>(&self, name: SavedDataName) -> Result<T>

where T: DeserializeOwned + Default,

Loads saved data, or returns T::default() when the data file is absent or this world has no persistent storage.

pub fn sync_save_wincode<T>( &self, name: WincodeSavedDataName, data: &T, ) -> Result<()>

where T: SchemaWrite<DefaultConfig, Src = T>,

Saves a versioned wincode value.

pub async fn save<T>(&self, name: SavedDataName, data: &T) -> Result<()>

where T: Serialize,

Saves a typed saved-data value.

fn path_for(&self, name: SavedDataName) -> Option<PathBuf>

fn wincode_path_for(&self, name: WincodeSavedDataName) -> Option<PathBuf>
