Simple Environment variable setter which loads a specified file, reads the key value pairs from each new line, and inserts them into the runtime environment. example:

EnvironmentLoader::new(file_path.to_str().unwrap());

Where file_path is a &str path to the desired env to load, and its content is as follows:

E1=123
E2=ABC

The result would be environment variables (E1, E2) being set with the specified values after the first = sign.

A code snippet example for a use case:

use std::{fmt::Result, fs::metadata};

let config_path = "config/server.env";
match metadata(config_path) {
Ok(_) => envloader::EnvironmentLoader::new(config_path),
Err(_) => println!("Using system environment"),
}
