Implementations

impl EpistemicGpuRuntimeWcojCertification

pub fn for_preflight_and_delta( preflight: &EpistemicGpuRuntimePreflight, delta: &EpistemicGpuRuntimeCounters, ) -> Self

Compare static preflight obligations with runtime counter deltas.

pub fn try_for_preflight_and_delta( preflight: &EpistemicGpuRuntimePreflight, delta: &EpistemicGpuRuntimeCounters, ) -> Result<Self>

Compare static preflight obligations with runtime counter deltas, failing closed if certification counters overflow while being summarized.

Trait Implementations

impl Clone for EpistemicGpuRuntimeWcojCertification

fn clone(&self) -> EpistemicGpuRuntimeWcojCertification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpistemicGpuRuntimeWcojCertification

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

Formats the value using the given formatter.

impl PartialEq for EpistemicGpuRuntimeWcojCertification

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