Struct TraceJitCompiler 

pub struct TraceJitCompiler { /* private fields */ }

Tier-2 trace-JIT compiler and dispatch cache.

Monitors superinstruction plan executions and promotes hot plans to JIT-compiled dispatch stubs when they reach the hotness threshold.

Implementations

impl TraceJitCompiler

pub fn new(config: TraceJitConfig) -> Self

Create a new JIT compiler with the given config.

pub const fn enabled(&self) -> bool

Whether the JIT tier is enabled.

pub const fn config(&self) -> &TraceJitConfig

Access the current config.

pub const fn telemetry(&self) -> &TraceJitTelemetry

Get a telemetry snapshot.

pub fn cache_size(&self) -> usize

Number of compiled traces in cache.

pub fn record_plan_execution( &mut self, plan: &HostcallSuperinstructionPlan, ) -> bool

Record that a superinstruction plan was executed at tier-1.

If the plan reaches the hotness threshold, it is promoted to JIT. Returns true if the plan was promoted.

pub fn try_jit_dispatch( &mut self, plan_id: &str, trace: &[String], ctx: &GuardContext, ) -> JitExecutionResult

Attempt JIT dispatch for a given trace and plan ID.

Returns a JitExecutionResult indicating whether JIT was used and any deoptimization reason.

pub fn get_compiled_trace(&self, plan_id: &str) -> Option<&CompiledTrace>

Look up a compiled trace by plan ID (read-only).

pub fn is_invalidated(&self, plan_id: &str) -> bool

Check if a plan ID has been invalidated.

pub fn reset(&mut self)

Reset all state (for testing or recalibration).

Trait Implementations

impl Clone for TraceJitCompiler

fn clone(&self) -> TraceJitCompiler

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

Performs copy-assignment from source.

impl Debug for TraceJitCompiler

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

Formats the value using the given formatter.

impl Default for TraceJitCompiler

fn default() -> Self

Returns the “default value” for a type.
