Function std::env::split_paths

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

根据平台约定对 PATH 环境变量解析输入。

返回 unparsed 中包含的路径上的迭代器。 迭代器元素类型为 PathBuf。

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.")
}
