Struct EquivalencePolicy 

pub struct EquivalencePolicy {
    pub clock_spread: f64,
    pub mem_spread: f64,
    pub chassis_delta_c: f64,
}

2026-09-26: The tolerances, read from the class’s HARDWARE.toml by EquivalencePolicy::speed.

Fields

clock_spread: f64

2026-09-26: Largest |a - b| / max(a, b) on the clock ceiling.

mem_spread: f64

2026-09-26: Largest |a - b| / max(a, b) on memory.

chassis_delta_c: f64

2026-09-26: Largest |a - b| on the hottest chassis zone, °C.

Implementations

impl EquivalencePolicy

pub fn speed(limits: &Limits) -> Self

2026-09-26: The policy for one hardware class, from its declared limits (kernels/<hw>/HARDWARE.toml [benchmarks.limits.equivalence] and .thermal): clock and memory spreads and the chassis delta, on GB10 1 %, 5 % and 15 °C.

pub fn speed_for(root: &Path, hardware: &str) -> Result<Option<Self>>

2026-09-26: The policy for hardware; None when it declares no limits.

Errors

Whatever super::limits::limits refuses: a missing, malformed or self-contradicting HARDWARE.toml.

Trait Implementations

impl Clone for EquivalencePolicy

fn clone(&self) -> EquivalencePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EquivalencePolicy

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

Formats the value using the given formatter.

impl PartialEq for EquivalencePolicy

fn eq(&self, other: &EquivalencePolicy) -> 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.
