Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, run:
source "$HOME/.cargo/env

$ cargo new hello
     Created binary (application) `hello` package
$ cd hello
$ cargo run
   Compiling hello v0.1.0 (/Users/sakti/dev/hello)
    Finished dev [unoptimized + debuginfo] target(s) in 0.56s
     Running `target/debug/hello`
Hello, world!
$ cat src/main.rs
fn main() {
    println!("Hello, world!");
}
