Function std::env::vars_os1.0.0[−][src]
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);
