aion-store 0.1.0

//! Persistence contracts and in-memory event stores for Aion durable workflows.
//!
//! The crate defines the async event-store traits used by the engine, visibility
//! records for workflow listings, timer records, run-chain summaries, and a
//! correct `InMemoryStore` reference implementation for tests and development.
//!
//! # Example
//!
//! ```
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! use aion_store::{InMemoryStore, ReadableEventStore, WorkflowId};
//!
//! let store = InMemoryStore::default();
//! let workflow_id = WorkflowId::new_v4();
//! let history = store.read_history(&workflow_id).await?;
//! assert!(history.is_empty());
//! # Ok(())
//! # }
//! ```
