Struct InMemoryDataService 

pub struct InMemoryDataService<T: Data> { /* private fields */ }

In-memory implementation of DataService

Provides a generic in-memory store for any entity type implementing Data. Useful for testing, development, and prototyping without external dependencies.

Uses Arc<RwLock<HashMap>> for thread-safe concurrent access.

Example

use this::storage::InMemoryDataService;

let service = InMemoryDataService::<MyEntity>::new();
let entity = service.create(my_entity).await?;
let found = service.get(&entity.id()).await?;
