Module rollback 

Execution rollback mechanism for workflows

This module provides the ability to create snapshots of execution state and rollback to previous states when needed.

Features

• Create point-in-time snapshots of execution state
• Store execution history with automatic pruning
• Rollback to any previous snapshot
• Support for selective rollback (specific variables, node results)

Example

use oxify_model::rollback::{ExecutionSnapshot, RollbackManager};
use oxify_model::execution::ExecutionContext;
use uuid::Uuid;

let mut manager = RollbackManager::new(10); // Keep 10 snapshots max
let mut context = ExecutionContext::new(Uuid::new_v4());

// Create a snapshot before risky operation
let snapshot = ExecutionSnapshot::from_context(&context);
manager.push_snapshot(snapshot);

// If operation fails, rollback
let result = manager.rollback(&mut context);
assert!(result.success);
