Trait Implementations

impl<A: Clone + Attribute> Clone for EavPickleStorage<A>

fn clone(&self) -> EavPickleStorage<A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Attribute> Debug for EavPickleStorage<A>

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

Formats the value using the given formatter.

impl<A: Attribute> EntityAttributeValueStorage<A> for EavPickleStorage<A> where
    A: Sync + Send + DeserializeOwned, 

fn add_eavi(
    &mut self,
    eav: &EntityAttributeValueIndex<A>
) -> PersistenceResult<Option<EntityAttributeValueIndex<A>>>

Adds the given EntityAttributeValue to the EntityAttributeValueStorage append only storage.

fn fetch_eavi(
    &self,
    query: &EaviQuery<A>
) -> PersistenceResult<BTreeSet<EntityAttributeValueIndex<A>>>

Fetch the set of EntityAttributeValues that match constraints according to the latest hash version - None = no constraint - Some(Entity) = requires the given entity (e.g. all a/v pairs for the entity) - Some(Attribute) = requires the given attribute (e.g. all links) - Some(Value) = requires the given value (e.g. all entities referencing an Address)

impl<A: Attribute> ReportStorage for EavPickleStorage<A> where
    A: Sync + Send + DeserializeOwned, 

fn get_storage_report(&self) -> PersistenceResult<StorageReport>

Return the number of bytes this storage implementation is using on the host system. The actual implementation is up to the author of the persistence implementation and may be disk usage or memory usage
