Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Attribute> Default for EavMemoryStorage<A>

fn default() -> EavMemoryStorage<A>

Returns the "default value" for a type.

impl<A: Attribute> PartialEq<EavMemoryStorage<A>> for EavMemoryStorage<A>

fn eq(&self, other: &EavMemoryStorage<A>) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<A: Debug + Attribute> Debug for EavMemoryStorage<A>

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

Formats the value using the given formatter.

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

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 EavMemoryStorage<A>

fn get_storage_report(&self) -> Result<StorageReport, PersistenceError>

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
