Exacl  

Rust library to manipulate file system access control lists (ACL) on macOS, Linux, and FreeBSD.

Example

use exacl::{getfacl, setfacl, AclEntry, Perm};

// Get the ACL from "./tmp/foo".
let mut acl = getfacl("./tmp/foo", None)?;

// Print the contents of the ACL.
for entry in &acl {
    println!("{}", entry);
}

// Add an ACL entry to the end.
acl.push(AclEntry::allow_user("some_user", Perm::READ, None));

// Set the ACL for "./tmp/foo".
setfacl(&["./tmp/foo"], &acl, None)?;

High Level API

This module provides two high level functions, getfacl and setfacl.

• getfacl retrieves the ACL for a file or directory.
• setfacl sets the ACL for files or directories.

On Linux and FreeBSD, the ACL contains entries for the default ACL, if present.

Both getfacl and setfacl work with a Vec<AclEntry>. The AclEntry structure contains five fields:

• kind : AclEntryKind - the kind of entry (User, Group, Other, Mask, or Unknown).
• name : String - name of the principal being given access. You can use a user/group name, decimal uid/gid, or UUID (on macOS).
• perms : Perm - permission bits for the entry.
• flags : Flag - flags indicating whether an entry is inherited, etc.
• allow : bool - true if entry is allowed; false means deny. Linux only supports allow=true.

Low Level API

Use the Acl class if you need finer grained control over the ACL.

• Manipulate the access ACL and default ACL independently on Linux.
• Manipulate the ACL's own flags on macOS.
• Use the platform specific text formats.
