Struct MemoryBackend 

pub struct MemoryBackend { /* private fields */ }

Separate in-memory backend that stores wire-envelope bytes.

This backend is not a replacement for L1; it exists to test the CacheBackend path without a Redis or filesystem dependency. It does not publish invalidation streams, so it should not be used as a coherence test double for distributed invalidation behavior.

Trait Implementations

impl<T> CacheBackend<T> for MemoryBackend

where T: Cacheable + Serialize + DeserializeOwned, T::Id: Serialize + DeserializeOwned,

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, keyspace: &'life1 BackendKeyspace, id: &'life2 T::Id, ) -> Pin<Box<dyn Future<Output = Result<Option<T>, BackendError>> + Send + 'async_trait>>

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

Read an entry from the backend.

fn put<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, keyspace: &'life1 BackendKeyspace, id: &'life2 T::Id, value: &'life3 T, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<(), BackendError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Store an entry in the backend.

fn invalidate<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, keyspace: &'life1 BackendKeyspace, id: &'life2 T::Id, ) -> Pin<Box<dyn Future<Output = Result<(), BackendError>> + Send + 'async_trait>>

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

Invalidate one backend entry and publish an id-scoped invalidation if supported.

fn invalidate_all<'life0, 'life1, 'async_trait>( &'life0 self, keyspace: &'life1 BackendKeyspace, ) -> Pin<Box<dyn Future<Output = Result<(), BackendError>> + Send + 'async_trait>>

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

Invalidate backend entries in this keyspace and publish an all-scoped invalidation if supported.

fn invalidation_stream( &self, _keyspace: BackendKeyspace, ) -> BackendInvalidationStream<T::Id>

Subscribe to backend invalidations for one keyspace.

impl Default for MemoryBackend

fn default() -> MemoryBackend

Returns the “default value” for a type.
