Function env_file_reader::read_file

pub fn read_file<P: AsRef<Path>>(
    path: P
) -> Result<HashMap<String, String>, Error>

Parses the environment file at the specified path.

Returns an error if reading the file was unsuccessful or if the file is ill-formatted. Read the crate’s documentation for information about the format that env-file-reader supports.

Example:

examples/.env:

CLIENT_ID=YOUR_CLIENT_ID
CLIENT_SECRET=YOUR_CLIENT_SECRET

use env_file_reader::read_file;

fn main() -> std::io::Result<()> {
  let env_variables = read_file("examples/.env")?;

  assert_eq!(&env_variables["CLIENT_ID"], "YOUR_CLIENT_ID");
  assert_eq!(&env_variables["CLIENT_SECRET"], "YOUR_CLIENT_SECRET");

  Ok(())
}
