Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.
vim main.rs
use ferris_says::say; // from the previous step
use std::io::{stdout, BufWriter};
fn main() {
let stdout = stdout();
let message = String::from("Hello fellow Rustaceans!");
let width = message.chars().count();
let mut writer = BufWriter::new(stdout.lock());
say(message.as_bytes(), width, &mut writer).unwrap();
}
Run
