Function secure_dealloc 

pub unsafe fn secure_dealloc(ptr: *mut u8, size: usize)

Secure memory deallocation with enhanced security

Deallocates memory securely by zeroing it before deallocation. Implements secure deallocation best practices including:

• Secure zeroing before deallocation
• Multiple passes of zeroing for sensitive data
• Compiler barriers to prevent optimization
• Proper layout reconstruction for deallocation

Arguments

• ptr - Pointer to memory to deallocate
• size - Size of memory to deallocate

Safety

This function is unsafe because it:

• Takes a raw pointer that must be valid for the given size
• The pointer must have been allocated with the same allocator
• The size must match the size used for allocation

Security

This function securely deallocates memory by zeroing it first to prevent data leakage.
