Struct JsonFileStore 

pub struct JsonFileStore { /* private fields */ }

JSON file-backed store for durable pool state.

Tasks are stored as individual JSON files under {dir}/tasks/{id}.json and slots under {dir}/slots/{id}.json. This makes state inspectable with standard tools and survives process restarts.

Implementations

impl JsonFileStore

pub async fn new(dir: impl Into<PathBuf>) -> Result<Self>

Create a new JSON file store rooted at dir.

Creates the directory structure (tasks/, slots/) if it does not exist.

pub fn dir(&self) -> &Path

Get the base directory.
