pub fn split_paths<T: AsRef<OsStr> + ?Sized>(unparsed: &T) -> SplitPaths<'_>

Examples

use std::env;

let key = "PATH";
match env::var_os(key) {
    Some(paths) => {
        for path in env::split_paths(&paths) {
            println!("'{}'", path.display());
        }
    }
    None => println!("{key} is not defined in the environment.")
}
