Struct BackendOptimizationTrace 

pub struct BackendOptimizationTrace {
    pub backend: OptimizationBackend,
    pub optimizer: FiredOptimizations,
    pub lowering: FiredOptimizations,
    pub declines: Vec<OptimizationDecline>,
    pub fallbacks: Vec<OptimizationFallback>,
}

Stage-separated optimization evidence for one backend compile/run.

optimizer contains shared IR/AST transformations. lowering contains choices that fired only while the selected backend emitted or compiled its target. Keeping these sets separate is the ratchet: a shared pass reaching C can no longer be mistaken for the C emitter actually preserving/consuming its optimized form.

Fields

backend: OptimizationBackend

optimizer: FiredOptimizations

lowering: FiredOptimizations

declines: Vec<OptimizationDecline>

fallbacks: Vec<OptimizationFallback>

Implementations

impl BackendOptimizationTrace

pub fn all_fired(&self) -> FiredOptimizations

Compatibility union used by the original single-bitset trace API.

Trait Implementations

impl Clone for BackendOptimizationTrace

fn clone(&self) -> BackendOptimizationTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendOptimizationTrace

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

Formats the value using the given formatter.

impl PartialEq for BackendOptimizationTrace

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