Struct FileSessionStore 

pub struct FileSessionStore { /* private fields */ }

Durable session store backed by per-session JSON files.

Session snapshots are cached in-memory for fast reads and also persisted on every save so process restarts can recover context.

Implementations

impl FileSessionStore

pub fn new(root: PathBuf) -> Result<Self, StoreError>

Create a file-backed store rooted at root.

Errors

Returns a backend error when the root directory cannot be created.

Trait Implementations

impl Debug for FileSessionStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SessionStore for FileSessionStore

fn load<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 SessionId, ) -> Pin<Box<dyn Future<Output = Result<Option<SessionState>, StoreError>> + Send + 'async_trait>>

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

Load a session by ID. Returns None if not found.

fn save<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 SessionId, state: &'life2 SessionState, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

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

Persist a session by ID. Increments the version unconditionally.

fn save_if_version<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 SessionId, state: &'life2 SessionState, expected_version: u64, ) -> Pin<Box<dyn Future<Output = Result<u64, StoreError>> + Send + 'async_trait>>

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

Persist a session only if the current version matches expected_version.
