Golang style error handling

cargo add anyhow

// return fmt.Errorf("error, when something. Error: %v", err)
io::stdin()
    .read_to_end(&mut input)
    .with_context(|| "failed to read from standard in")?;

// return errors.New("error, thing happened bad bad")
io::stdin()
    .read_to_end(&mut input)
    .context("failed to read from standard in")?;

Random

cargo add rand

// using golang crypto/rand equivalent by default
use rand::Rng;

const CHARSET: &[u8] = b"abcdefghijklmnopqrstuvwxyz0123456789";

fn random_string(len: usize) -> String {
    let mut rng = rand::rng();

    (0..len)
        .map(|_| {
            let idx = rng.random_range(0..CHARSET.len());
            CHARSET[idx] as char
        })
        .collect()
}
