A Small Rust Application
Generate a new project:
cargo new hello-rust
cd hello-rust
Run the default program:
cargo run
Add a dependency via CLI:
cargo add ferris-says
Then build (Cargo will install our dependency for us):
cargo build
This will also generate Cargo.lock
(dependency versions lockfile).
Edit src/main.rs
:
use ferris_says::say;
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, width, &mut writer).unwrap();
}
Run it:
cargo run
