Struct InMemorySessionStore 

pub struct InMemorySessionStore(/* private fields */);

An in-memory session store.

Limitations

This store won’t persist data between server restarts. It also won’t synchronize data between multiple server instances. It is primarily intended for testing and local development.

Implementations

impl InMemorySessionStore

pub fn new() -> Self

Creates a new (empty) in-memory session store.

Trait Implementations

impl Clone for InMemorySessionStore

fn clone(&self) -> InMemorySessionStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InMemorySessionStore

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

Formats the value using the given formatter.

impl Default for InMemorySessionStore

fn default() -> Self

Returns the “default value” for a type.

impl From<InMemorySessionStore> for SessionStore

fn from(value: InMemorySessionStore) -> Self

Converts to this type from the input type.

impl SessionStorageBackend for InMemorySessionStore

fn create<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 SessionId, record: SessionRecordRef<'life2>, ) -> Pin<Box<dyn Future<Output = Result<(), CreateError>> + Send + 'async_trait>>

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

Creates a new session record in the store using the provided ID.

fn update<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, id: &'life1 SessionId, record: SessionRecordRef<'life2>, ) -> Pin<Box<dyn Future<Output = Result<(), UpdateError>> + Send + 'async_trait>>

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

Update the state of an existing session in the store.

It overwrites the existing record with the provided one.

fn update_ttl<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 SessionId, ttl: Duration, ) -> Pin<Box<dyn Future<Output = Result<(), UpdateTtlError>> + Send + 'async_trait>>

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

Update the TTL of an existing session record in the store.

It leaves the session state unchanged.

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

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

Loads an existing session record from the store using the provided ID.

If a session with the given ID exists, it is returned. If the session does not exist or has been invalidated (e.g., expired), None is returned.

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

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

Deletes a session record from the store using the provided ID.

If the session exists, it is removed from the store.

fn change_id<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, old_id: &'life1 SessionId, new_id: &'life2 SessionId, ) -> Pin<Box<dyn Future<Output = Result<(), ChangeIdError>> + Send + 'async_trait>>

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

Change the session id associated with an existing session record.

The server-side state is left unchanged.

fn delete_expired<'life0, 'async_trait>( &'life0 self, batch_size: Option<NonZeroUsize>, ) -> Pin<Box<dyn Future<Output = Result<usize, DeleteExpiredError>> + Send + 'async_trait>>

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

Delete all expired records from the store.
