Struct InMemoryManagedStateStore 

pub struct InMemoryManagedStateStore { /* private fields */ }

The in-memory managed state store.

The default, and the only implementation that ships. Named explicitly so its guarantee is visible at the call site rather than implied by the absence of an alternative.

Implementations

impl InMemoryManagedStateStore

pub fn new() -> Self

Creates an empty store.

Trait Implementations

impl Debug for InMemoryManagedStateStore

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

Formats the value using the given formatter.

impl Default for InMemoryManagedStateStore

fn default() -> InMemoryManagedStateStore

Returns the “default value” for a type.

impl ManagedStateStore for InMemoryManagedStateStore

fn durability(&self) -> Durability

What this store guarantees after process loss.

fn save<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, state: ManagedSessionState, ) -> Pin<Box<dyn Future<Output = Result<(), RuntimeError>> + Send + 'async_trait>>

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

Records the state of session_id, replacing any previous snapshot.

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

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

The recorded state for session_id, or None when nothing is stored.

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

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

Removes any state for session_id.

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

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

The sessions this store holds state for.
