Struct MachineIdentity 

pub struct MachineIdentity {
    pub hostname: Option<String>,
    pub machine_id: Option<String>,
    pub gpu: Option<String>,
    pub driver: Option<String>,
}

2026-09-26: Which individual box this is. super::Hardware::gate_key gives the silicon class ("gb10") that baselines are keyed by; this tells two boxes of one class apart.

Fields

hostname: Option<String>

machine_id: Option<String>

2026-09-26: /etc/machine-id, which a hostname change does not alter.

gpu: Option<String>

driver: Option<String>

Implementations

impl MachineIdentity

pub fn perf_class(&self) -> String

2026-09-26: "gb10@dgx1": silicon class, then hostname.

An absent half reads "unknown" rather than being dropped, so two records with different missing halves never collapse to the same string.

Trait Implementations

impl Clone for MachineIdentity

fn clone(&self) -> MachineIdentity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MachineIdentity

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

Formats the value using the given formatter.

impl Default for MachineIdentity

fn default() -> MachineIdentity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MachineIdentity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MachineIdentity

fn eq(&self, other: &MachineIdentity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MachineIdentity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
