Struct InMemoryCheckpointStore 

pub struct InMemoryCheckpointStore<S> { /* private fields */ }

In-memory checkpoint store backed by a RwLock<HashMap>.

Suitable for tests and single-process usage where durability is not required. Production deployments should implement CheckpointStore with durable storage (e.g. SQLite via khive-db).

Implementations

impl<S> InMemoryCheckpointStore<S>

pub fn new() -> Self

Create a new empty in-memory store.

Trait Implementations

impl<S: Clone + Send + Sync + Serialize + 'static> CheckpointStore<S> for InMemoryCheckpointStore<S>

fn save(&self, checkpoint: Checkpoint<S>) -> Result<(), FoldError>

where S: Clone + Serialize,

Persist a checkpoint, computing and storing an integrity hash.

fn load(&self, id: &str) -> Result<Option<Checkpoint<S>>, FoldError>

where S: Clone + Serialize,

Load a checkpoint by its exact id, verifying the integrity hash.

fn load_latest(&self, prefix: &str) -> Result<Option<Checkpoint<S>>, FoldError>

where S: Clone + Serialize,

Load the most recently created checkpoint whose id starts with prefix.

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

Delete the checkpoint with the given id.

fn list(&self) -> Result<Vec<String>, FoldError>

List all checkpoint id strings currently stored.

impl<S> Default for InMemoryCheckpointStore<S>

fn default() -> Self

Returns the “default value” for a type.
