Struct InMemoryAtomStore 

pub struct InMemoryAtomStore<V: Clone> { /* private fields */ }

A HashMap-backed AtomStore for any Clone atom type.

Kind/tag filtering in AtomStore::query_atoms is deferred to the domain layer — this implementation returns all atoms subject only to limit/offset pagination.

Implementations

impl<V: Clone> InMemoryAtomStore<V>

pub fn new() -> Self

Create an empty store.

pub fn len(&self) -> usize

Number of atoms currently stored.

pub fn is_empty(&self) -> bool

Returns true if the store is empty.

Trait Implementations

impl<V: Clone + HasAtomId> AtomStore for InMemoryAtomStore<V>

type Atom = V

The atom value type stored and retrieved by this implementation.

fn get_atom(&self, id: AtomId) -> Result<&V, StoreError>

Retrieve an atom by its ID.

fn put_atom(&mut self, atom: V) -> Result<(), StoreError>

Insert or replace an atom. The atom’s ID is used as the key.

fn delete_atom(&mut self, id: AtomId) -> Result<(), StoreError>

Delete an atom by ID. Returns StoreError::NotFound if absent.

fn query_atoms(&self, query: &Query) -> Result<QueryResult<&V>, StoreError>

Return a paged, optionally-filtered collection of atoms.

impl<V: Debug + Clone> Debug for InMemoryAtomStore<V>

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

Formats the value using the given formatter.

impl<V: Default + Clone> Default for InMemoryAtomStore<V>

fn default() -> InMemoryAtomStore<V>

Returns the “default value” for a type.
