Function tracing::stdlib::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.

Note that the returned iterator will not check if the environment variables are valid Unicode. If you want to panic on invalid UTF-8, use the vars function instead.

Examples

// Print all environment variables.
for (key, value) in std::env::vars_os() {
    println!("{key:?}: {value:?}");
}
