Function chroot 

pub fn chroot<P: AsRef<Path>>(dir: P) -> Result<()>

Available on non-Hermit and (Unix) and not ((WebAssembly and non-WASI, or Fortanix and SGX)) and non-Fuchsia only.

Change the root directory of the current process to the specified path.

This typically requires privileges, such as root or a specific capability.

This does not change the current working directory; you should call std::env::set_current_dir afterwards.

Examples

use std::os::unix::fs;

fn main() -> std::io::Result<()> {
    fs::chroot("/sandbox")?;
    std::env::set_current_dir("/")?;
    // continue working in sandbox
    Ok(())
}
