Function boolean_enums::lstd::env::vars_os

Important traits for VarsOs

impl Iterator for VarsOs type Item = (OsString, OsString);

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

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);
}
