✓ Aliasing XOR Mutability satisfied. Zero data races detected.
3. Under The Hood: Py vs Rs vs C++
🐍 Python (CPython GC)
Passes pointers by reference. All variables increment PyObject.ob_refcnt. Memory freed asynchronously by GC cycle when refcount reaches 0.
🦀 Rust (Affine Types)
Variable ownership moves at compile time. No garbage collection, no runtime overhead. Automatically deallocates (Drop) at end of owner scope.
⚙️ C++ (Manual / UB Risk)
Copy-by-default or raw pointers. Double-free, use-after-free, or iterator invalidation compiles cleanly but causes undefined behavior at runtime.
💡 Why learn Rust after Python?
Rust teaches you the true hardware reality of memory, cache lines, and data layouts without allowing you to crash or corrupt memory with undefined behavior.
