Struct MemorySessionStore 

pub struct MemorySessionStore { /* private fields */ }

In-process SessionStore backed by a HashMap of HashSets. Suitable for tests, single-process deployments, and as the default when no distributed store is configured. Cloning the store via Arc shares state across all consumers.

Implementations

impl MemorySessionStore

pub fn new() -> MemorySessionStore

A new instance with nothing registered or stored yet.

pub fn snapshot(&self) -> HashMap<String, HashSet<String>>

Snapshot the entire store. Test/diagnostic helper — production callers should go through the trait so the backing implementation stays swappable.

Trait Implementations

impl Default for MemorySessionStore

fn default() -> MemorySessionStore

Returns the “default value” for a type.

impl SessionStore for MemorySessionStore

fn load_labels<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, SessionStoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, MemorySessionStore: 'async_trait,

Load the union of labels accumulated for the session. Ok(empty) for new or unknown sessions (a confirmed key-miss); Err only on a backend failure.

fn append_labels<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_id: &'life1 str, labels: &'life2 [String], ) -> Pin<Box<dyn Future<Output = Result<(), SessionStoreError>> + Send + 'async_trait>>

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

Append labels to the session. Existing labels are kept; new ones are unioned in. Caller has already deduped against load_labels in the hot path, but the store re-dedups defensively. Err only on a backend failure.
