rust-script

Run Rust script files without any setup or explicit compilation step, with seamless use of crates specified as dependencies inside the scripts.

$ cargo install rust-script
[...]

$ cat script.rs
#!/usr/bin/env rust-script
//! Dependencies can be specified in the script file itself as follows:
//!
//! ```cargo
//! [dependencies]
//! rand = "0.8.0"
//! ```

use rand::prelude::*;

fn main() {
    let x: u64 = random();
    println!("A random number: {}", x);
}

$ ./script.rs
A random number: 9240261453149857564

Rust version 1.74 or newer required.
