1//! Pure domain model and shared vocabulary for Aion durable workflows.
2//!
3//! This leaf crate defines the stable identifiers, payload carrier, history events,
4//! workflow filters, schedule settings, search attributes, statuses, and error
5//! taxonomy used by every other Aion component.
6//!
7//! # Example
8//!
9//! ```
10//! use aion_core::{Payload, WorkflowId};
11//! use serde_json::json;
12//!
13//! let workflow_id = WorkflowId::new_v4();
14//! let payload = Payload::from_json(&json!({ "workflow_id": workflow_id.to_string() }))?;
15//! assert_eq!(payload.to_json()?["workflow_id"], workflow_id.to_string());
16//! # Ok::<(), Box<dyn std::error::Error>>(())
17//! ```
