Function rustful::file::check_path

pub fn check_path<P: ?Sized + AsRef<Path>>(path: &P) -> Result<(), Component>

Check if a path tries to escape its parent directory.

Forbidden path components:

• Root directory
• Prefixes (e.g. C: on Windows)
• Parent directory

Allowed path components:

• "Normal" components (e.g. res/scripts)
• Current directory

The first forbidden component is returned if the path is invalid.

use std::path::Component;
use rustful::file::check_path;

let bad_path = "..";

assert_eq!(check_path(bad_path), Err(Component::ParentDir));
