unix-cred

A Rust library that simplifies reading peer credentials from Unix sockets.

Example:

```rust use std::os::unix::net::UnixStream;

fn main() { let (sock, _peer) = UnixStream::pair().unwrap();

// This will print the UID/GID of the current process
// (since it's in possession of the other end)
let (uid, gid) = unix_cred::get_peer_ids(&sock).unwrap();
println!("{} {}", uid, gid);

// Retrieving the PID is not supported on all platforms
// (and on some versions of some platforms None will be returned)
// See the documentation for more details
let (pid, uid, gid) = unix_cred::get_peer_pid_ids(&sock).unwrap();
println!("{:?} {} {}", pid, uid, gid);

} ```

Platform support

The following platforms have first-class support (tests are run in CI, and everything should work):

• Linux (glibc and musl)
• FreeBSD
• macOS

The following platforms have second-class support (built, but not tested, in CI):

• NetBSD

The following platforms have third-class support (not even built in CI):

• OpenBSD
• DragonFlyBSD
