Struct JsonFileAdapter 

pub struct JsonFileAdapter { /* private fields */ }

A JSON-file persistence backend. Each session is stored as <dir>/<id>.json. Suitable for local single-node deployments where Postgres (MVP 4) is not available.

Implementations

impl JsonFileAdapter

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

Create an adapter rooted at dir.

The directory is created lazily when a session is saved.

impl PersistenceAdapter for JsonFileAdapter

fn save_session<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 str, data: &'life2 Value, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Persist a session’s serialized state.

fn load_session<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Value>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load a session’s serialized state.

fn list_sessions<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

List all known session ids (for discovery / --resume).
