Rust connection url example is incorrect

[oscartbeaumont]

When getting the connection URL from Planetscale it shows snippets from a bunch of different programming languages to help get you started. The Rust examples shows putting the connection URL in a .env file and then also adding dotenv as a dependency however the dotenv.ok(); line is never shown in the src/main.rs. This line is required so the environment variable is read from the .env file.

Fix by changing src/main.rs to:

use std::env;
use dotenv::dotenv;

fn main() {
    dotenv.ok();
    let url = env::var("DATABASE_URL").expect("DATABASE_URL not found");
    let builder = mysql::OptsBuilder::from_opts(mysql::Opts::from_url(&url).unwrap());
    let pool = mysql::Pool::new(builder.ssl_opts(mysql::SslOpts::default())).unwrap();
    let _conn = pool.get_conn().unwrap();
    println!("Successfully connected to PlanetScale!");
}
