Enum SessionBackend 

pub enum SessionBackend {
    Sqlite(SqliteSessionStore),
    CloudflareKv(KvSessionStore),
}

Pluggable session storage backend

Variants

Sqlite(SqliteSessionStore)

Local SQLite storage (default)

CloudflareKv(KvSessionStore)

Cloudflare Workers KV via REST API

Implementations

impl SessionBackend

pub async fn create(&self) -> Result<Session>

Create a new session

pub async fn get(&self, id: &str) -> Result<Option<Session>>

Get a session by ID

pub async fn get_or_create(&self, id: Option<&str>) -> Result<Session>

Get or create a session

pub async fn update(&self, id: &str, data: HashMap<String, Value>) -> Result<()>

Update session data

pub async fn touch(&self, id: &str) -> Result<()>

Update last accessed time

pub async fn delete(&self, id: &str) -> Result<()>

Delete a session

pub async fn cleanup_expired(&self) -> Result<u64>

Clean up expired sessions (no-op for KV which uses TTL)

pub async fn list_session_ids(&self) -> Result<Vec<String>>

List active session IDs (SQLite only, returns empty for KV)

pub async fn count(&self) -> Result<usize>

Count active sessions (SQLite only, returns 0 for KV)

pub async fn apply_mutation( &self, id: &str, mutation: &AtomicMutation, ) -> Result<HashMap<String, Value>>

Apply an atomic mutation directly at the storage level. For SQLite, this uses SQL json_set/json_extract for atomicity. For KV, falls back to read-modify-write (KV doesn’t support atomic ops). Returns the updated session data after the mutation.

Trait Implementations

impl Clone for SessionBackend

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
