🤖 Welcome to Claude CLI!
💭 Your message: Help me write a Rust function to calculate Fibonacci numbers

┌─────────────────────────────────────────────────────
│ Claude:
│ I'll help you create an efficient Rust function for calculating Fibonacci numbers.
│ Here's an implementation using dynamic programming:
│
│ 📄 fib.rs
│ fn fibonacci(n: u64) -> u64 {
│     if n <= 1 {
│         return n;
│     }
│
│     let mut a = 0;
│     let mut b = 1;
│
│     for _ in 2..=n {
│         let temp = a + b;
│         a = b;
│         b = temp;
│     }
│
│     b
│ }
│
│ Would you like me to save this file?
