UNIXPermissionsExt

A trivial trait bringing missing functions that are not exposed by std::os::unix::fs::PermissionsExt to std::fs::Permissions on UNIX platforms.

pub trait UNIXPermissionsExt {
    fn set_uid(&self) -> bool;
    fn set_gid(&self) -> bool;
    fn sticky_bit(&self) -> bool;

    fn readable_by_owner(&self) -> bool;
    fn writable_by_owner(&self) -> bool;
    fn executable_by_owner(&self) -> bool;

    fn readable_by_group(&self) -> bool;
    fn writable_by_group(&self) -> bool;
    fn executable_by_group(&self) -> bool;

    fn readable_by_other(&self) -> bool;
    fn writable_by_other(&self) -> bool;
    fn executable_by_other(&self) -> bool;
}

How to use

1. Add it to your dependency:

   $ cd $YOUR_PROJECT
   $ cargo add unix_permissions_ext
   

2. Import this trait and use it just like you are using the standard library!

   use std::fs;
   use unix_permissions_ext::UNIXPermissionsExt;
   
   let metadata = fs::metadata("/usr/bin/passwd").expect("can not fetch metadata");
   let permission = metadata.permissions();
   
   assert!(permission.set_uid());
