Creating a self-healing memory system is an advanced concept requiring hardware awareness, low-level programming, and AI/ML models.
Conceptual Overview of a Self-Healing Memory System
A self-healing memory system identifies, isolates, and mitigates memory errors (e.g., corrupted or unused memory) in real-time, minimizing system crashes or performance degradation.

/*
Design Explanation:
This project combines Rust's low-level memory management capabilities with AI-based anomaly detection to implement a self-healing memory system. Below are the design steps:
1. Memory Monitoring:
A custom global allocator (`TrackingAllocator`) is implemented using Rust's GlobalAlloc trait. This allocator intercepts memory allocation and deallocation calls, enabling us to track active memory blocks. Memory usage logs are printed to aid in debugging and analysis.
2. Memory Manager:
A MemoryManager struct, implemented as a singleton, maintains a thread-safe collection (`Mutex<HashSet>`) to track pointers to allocated memory blocks. It also provides a heal_memory function to reclaim unused memory by deallocating stale or unreferenced blocks.
3. AI Integration:
An AI model, created using the tch crate (a PyTorch binding for Rust), detects anomalies in memory usage patterns. A simple linear model is used to process memory data and identify unusual conditions. Anomalies trigger corrective actions.
4. Background Monitoring Task:
Using the tokio asynchronous runtime, a periodic task is run in the background. This task calls the heal_memory function at regular intervals to clean up unused memory blocks and maintain system stability.
5. Simulation of Memory Usage and AI Anomaly Detection:
The main function simulates typical memory allocations and invokes the anomaly detection function. Detected anomalies are logged, and corrective actions are initiated.
