A settings manager trait.

This type should handle the file loading and saving, and manage the paths of the files.

Required Methods

fn load_file<T: DeserializeOwned>(&self, path: impl AsRef<Path>) -> Result<T>

Load a file from specified path.

fn save_file<T: Serialize>( &self, path: impl AsRef<Path>, data: &T, pretty: bool, ) -> Result<()>

Save a file to specified path.

fn settings_path(&self) -> Result<PathBuf>

Get the settings path.

fn global_record_path(&self, game: &str) -> Result<PathBuf>

Get the global record path.

fn records_path( &self, game: &str, ) -> Result<impl Iterator<Item = Result<PathBuf>>>

Get an iterator of record paths.

fn record_path(&self, game: &str, i: usize) -> Result<PathBuf>

Get the record path from index.

Provided Methods

fn load_settings(&self) -> Result<Settings>

Load Settings.

fn save_settings(&self, data: &Settings) -> Result<()>

Save Settings.

fn load_global_record(&self, game: &str) -> Result<GlobalRecord>

Load GlobalRecord.

fn save_global_record(&self, game: &str, data: &GlobalRecord) -> Result<()>

Save GlobalRecord.

fn load_records(&self, game: &str) -> Result<Vec<ActionRecord>>

Load all ActionRecord.

fn save_records(&self, game: &str, contexts: &[ActionRecord]) -> Result<()>

Save all ActionRecord.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
