Struct Credentials 

pub struct Credentials { /* private fields */ }

Credentials of a peer connection.

Implementations

impl Credentials

pub fn unix_user_id(&self) -> Uid

The numeric Unix user ID, as defined by POSIX.

pub fn process_id(&self) -> Pid

The numeric process ID, on platforms that have this concept.

On Unix, this is the process ID defined by POSIX.

pub fn unix_primary_group_id(&self) -> Gid

The numeric Unix group ID, as defined by POSIX.

pub fn unix_supplementary_group_ids(&self) -> &[Gid]

The set of numeric supplementary Unix group IDs, as defined by POSIX.

Currently, this method is only available for Linux targets.

pub fn process_fd(&self) -> Option<BorrowedFd<'_>>

A file descriptor pinning the process, on platforms that have this concept.

On Linux, the SO_PEERPIDFD socket option is a suitable implementation. This is safer to use to identify a process than the ProcessID, as the latter is subject to re-use attacks, while the FD cannot be recycled. If the original process no longer exists the FD will no longer be resolvable. The SO_PEERPIDFD socket option was added to Linux in version 6.5. This method will return None on older kernel versions.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
