Struct OptimizationFallback 

pub struct OptimizationFallback {
    pub from: OptimizationBackend,
    pub to: OptimizationBackend,
    pub reason: String,
}

An explicit backend escape hatch taken while lowering. A fallback is data, never a silent control-flow edge: benchmark tooling can ratchet this list to zero without pretending the fallback backend performed the requested work.

Fields

from: OptimizationBackend

to: OptimizationBackend

reason: String

Trait Implementations

impl Clone for OptimizationFallback

fn clone(&self) -> OptimizationFallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizationFallback

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

Formats the value using the given formatter.

impl PartialEq for OptimizationFallback

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