Function dotenvy::from_filename_iter

pub fn from_filename_iter<P: AsRef<Path>>(filename: P) -> Result<Iter<File>>

Like from_filename, but returns an iterator over variables instead of loading into environment.

Examples

dotenvy::from_filename("custom.env").ok();

It is also possible to do the following, but it is equivalent to using dotenvy::dotenv(), which is preferred.

let iter = dotenvy::from_filename_iter(".env").unwrap();

for item in iter {
  let (key, val) = item.unwrap();
  println!("{}={}", key, val);
}
