Welcome to the Fibonacci in Rust page! Here, you'll find the source code for this program as well as a description of how the program works.

```
use std::env::args;
use std::process::exit;
use std::str::FromStr;
const LIMIT: i32 = 93;
fn usage() -> ! {
println!("Usage: please input the count of fibonacci numbers to output");
exit(0);
}
fn parse_int<T: FromStr>(s: &str) -> Result<T, <T as FromStr>::Err> {
s.trim().parse::<T>()
}
fn fibonacci(terms: i32) {
if terms > LIMIT {
println!("The number of terms you want to calculate is too big!");
println!("The limit is {}.", LIMIT);
} else {
let mut a = 0u64;
let mut b = 1u64;
for i in 1..(terms + 1) {
(a, b) = (b, a + b);
println!("{i}: {a}");
}
}
}
fn main() {
let mut args = args().skip(1);
// Exit if 1st command-line argument not an integer
let mut input_num: i32 = args
.next()
.and_then(|s| parse_int(&s).ok())
.unwrap_or_else(|| usage());
// Show request number of Fibonacci numbers
fibonacci(input_num);
}
```
