Macro pathsep::join_path

    () => { ... };

Join a path with the correct path separator

Examples

Join a relative path of three args

assert_eq!(join_path!("src","def","impl"),
    concat!("src", path_separator!(), "def", path_separator!(), "impl"));

Make the path absolute by prepending a /

assert_eq!(join_path!(/ "var","tmp"),
    concat!(path_separator!(), "var", path_separator!(), "tmp"));
