1. Language Basics: Syntax Comparison
i. Hello World
| Mojo: | Rust |
| fn main(): print(“Hello, Mojo!”) | fn main() { println!(“Hello, Rust!”); } |
ii. Variables and Types
| Mojo (Python-like, optional typing): | Rust (strong static typing): |
| let x = 10 # inferred var y: Int32 = 20 # explicit | let x = 10; // immutable let mut y: i32 = 20; // mutable |
2. Performance-Critical Code
Looping & Computation
| Mojo | Rust |
| fn sum_array(arr: [Int32]): var total = 0 for val in arr: total += val return total | fn sum_array(arr: &[i32]) -> i32 { let mut total = 0; for &val in arr { total += val; } total } |
3. Memory Safety & Ownership
| Rust: Borrow Checker Demo: | Mojo: No ownership model like Rust (Pythonic model): |
| fn main() { let s = String::from(“hello”); let s2 = s; // s is moved println!(“{}”, s); // compile-time error! }
| def use_string(s: String): print(s)
let s = “hello” use_string(s) # no ownership rules enforced
