[][src]Function dotenv::from_filename_iter

pub fn from_filename_iter<P: AsRef<Path>>(filename: P) -> Result<Iter<File>>
Deprecated since 0.14.1:

please use from_path in conjunction with var instead

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


use dotenv;

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

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

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