Performance Comparison
Memory Allocation
c
// C: Manual Memory Management (Vulnerable)
char* create_string(int size) {
char* buffer = malloc(size); // No size checking
if (!buffer) return NULL;
return buffer; // Caller responsible for free()
}
rust
// Rust: Safe Memory Allocation
fn create_string(size: usize) -> Option<Vec<u8>> {
// Automatic memory management
// Bounds checking
// Guaranteed memory safety
Some(vec![0; size])
}
Performance Benchmark
- C: Direct memory access
- Rust: Zero-cost abstractions with compile-time guarantees
- Rust achieves near-C performance with additional safety
Memory Management
C: Prone to Vulnerabilities
c
// Classic Buffer Overflow
void vulnerable_copy(char* dest, char* src) {
strcpy(dest, src); // No length validation
// Potential security exploit
}
Rust: Compile-Time Safety
rust
// Rust prevents buffer overflows
fn safe_copy(dest: &mut [u8], src: &[u8]) {
// Compile-time bounds checking
dest.copy_from_slice(&src[..dest.len()]);
}
Security Features
Memory Safety Comparison
-
C: Manual memory management
- Developers track memory allocation
- High risk of:
- Buffer overflows
- Use-after-free vulnerabilities
- Memory leaks
-
Rust: Ownership and Borrowing System
- Compile-time memory safety checks
- Ownership rules prevent:
- Dangling pointers
- Data races
- Undefined behavior

Complexity Analysis
c
// C: Complex Pointer Management
int* complex_pointer_logic(int* data, int size) {
int* result = malloc(size * sizeof(int));
if (!result) return NULL;
for (int i = 0; i < size; i++) {
// Manual memory tracking
result[i] = data[i] * 2;
}
return result;
}
rust
// Rust: Simplified Memory Handling
fn simplified_logic(data: &[i32]) -> Vec<i32> {
// Automatic memory management
// No malloc/free required
data.iter().map(|&x| x * 2).collect()
}

Concurrency Model
Python's Global Interpreter Lock (GIL)
python
import threading
def cpu_bound_task(n):
return sum(i * i for i in range(n))
# Limited true parallelism
threads = [threading.Thread(target=cpu_bound_task, args=(10_000_000,)) for _ in range(4)]

sum += i * i
}
ch <- sum
}
func main() {
