Function machine_id_raw 

Source 
pub fn machine_id_raw() -> Option<Vec<u8>>
Expand description

Raw, stable machine identifier bytes for the same-machine attestation fingerprint (RFC-001 amendment #182, same_machine::machine_fingerprint).

  • Linux: /etc/machine-id (systemd), falling back to /var/lib/dbus/machine-id.
  • macOS: IOPlatformUUID from ioreg -rd1 -c IOPlatformExpertDevice.
  • Windows: HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid (reg query).

Returns None on any read failure — the caller omits the attestation and the session still functions, it just can’t join the same-machine lane (fail-closed, §A). The bytes are used only as hash input; their exact encoding is irrelevant as long as it is stable for a given machine.
