Struct FileSystemPersistence 

pub struct FileSystemPersistence { /* private fields */ }

Simple file-based persistence implementation.

This implementation stores the state in a single file on disk. It provides persistent storage that survives process restarts.

Implementations

impl FileSystemPersistence

pub async fn new<P: AsRef<Path>>(data_dir: P) -> Result<Self>

Create a new file-based persistence instance.

Arguments

• data_dir - Directory path where the state file will be stored

Returns

• A new FileSystemPersistence instance

Errors

• Returns error if the data directory cannot be created

pub fn new_sync<P: AsRef<Path>>(data_dir: P) -> Result<Self>

Create a new file-based persistence instance (synchronous).

This is a convenience method that blocks on the async new method.

Arguments

• data_dir - Directory path where the state file will be stored

Returns

• A new FileSystemPersistence instance

Errors

• Returns error if the data directory cannot be created
