Function std::env::vars_os

pub fn vars_os() -> VarsOs

Returns an iterator of (variable, value) pairs of OS strings, for all the environment variables of the current process.

The returned iterator contains a snapshot of the process's environment variables at the time of this invocation, modifications to environment variables afterwards will not be reflected in the returned iterator.

Examples

fn main() { use std::env; // We will iterate through the references to the element returned by // env::vars_os(); for (key, value) in env::vars_os() { println!("{:?}: {:?}", key, value); } }

use std::env;

// We will iterate through the references to the element returned by
// env::vars_os();
for (key, value) in env::vars_os() {
    println!("{:?}: {:?}", key, value);
}
