Struct LockHolder 

pub struct LockHolder {
    pub identity: ProcessIdentity,
    pub executable: Option<PathBuf>,
    pub acquired_at: DateTime<Utc>,
    pub lock: LockKind,
}

Who holds a lock, as recorded by the holder itself.

Written into the lock file after the lock is taken, so that the process that loses the race can say something useful instead of “somebody else”.

Fields

identity: ProcessIdentity

The holder’s process identity — a PID alone would not survive being read back by a process that started after a reboot.

executable: Option<PathBuf>

The holder’s executable, when it could be resolved. 05-infrastructure.md requires service status to report a stale or moved binary path, and an operator looking at a contended lock has the same question.

acquired_at: DateTime<Utc>

When the lock was taken.

lock: LockKind

Which lock the record belongs to. Recorded so that a file opened by mistake is recognised rather than misreported.
