Struct OptimizationDecline 

pub struct OptimizationDecline {
    pub backend: OptimizationBackend,
    pub opt: Opt,
    pub reason: String,
}

A supported optimization that a backend deliberately chose not to apply.

This is distinct from OptimizationFallback: a decline stays on the requested backend and records a cost-model, proof, or capability decision; a fallback changes the backend that executes the program. Keeping the two channels separate lets benchmark ratchets reject silent backend changes without also rejecting an explicitly justified profitability decision.

Fields

backend: OptimizationBackend

opt: Opt

reason: String

Trait Implementations

impl Clone for OptimizationDecline

fn clone(&self) -> OptimizationDecline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizationDecline

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

Formats the value using the given formatter.

impl PartialEq for OptimizationDecline

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