Function dotenv::from_path_iter

pub fn from_path_iter(path: &Path) -> Result<Iter<File>>

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

Examples

use dotenv;
use std::env;
use std::path::{Path};

let my_path = env::home_dir().and_then(|a| Some(a.join("/.env"))).unwrap();
let iter = dotenv::from_path_iter(my_path.as_path()).unwrap();

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