Struct CompiledTrace 

pub struct CompiledTrace {
    pub plan_id: String,
    pub trace_signature: String,
    pub guards: Vec<TraceGuard>,
    pub opcode_window: Vec<String>,
    pub width: usize,

}

A compiled trace stub with guard conditions and dispatch metadata.

Fields

plan_id: String

Plan ID this trace was compiled from.

trace_signature: String

Trace signature (hash of opcode window).

guards: Vec<TraceGuard>

Guard conditions that must all hold for this trace to execute.

opcode_window: Vec<String>

The opcode window this trace covers.

width: usize

Width of the compiled trace (number of opcodes fused).

estimated_cost_jit: i64

Estimated cost of JIT dispatch (lower than tier-1 fused cost).

estimated_cost_fused: i64

Original tier-1 fused cost for comparison.

tier_improvement_delta: i64

Cost improvement over tier-1: fused - jit.

tier: CompilationTier

Compilation tier.

Implementations

impl CompiledTrace

pub fn from_plan(plan: &HostcallSuperinstructionPlan) -> Self

Create a compiled trace from a superinstruction plan.

pub fn guards_pass(&self, trace: &[String], ctx: &GuardContext) -> bool

Check all guards against the given trace and context.

Trait Implementations

impl Clone for CompiledTrace

fn clone(&self) -> CompiledTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompiledTrace

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompiledTrace

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CompiledTrace

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

impl Serialize for CompiledTrace

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
