Struct JitEntry

pub struct JitEntry {
    pub invocation_count: AtomicU32,
    pub lower_queued: AtomicBool,
    pub compile_queued: AtomicBool,
    pub native_fn_ptr: AtomicPtr<()>,

}

Fields§

§invocation_count: AtomicU32§lower_queued: AtomicBool

A background IR-lowering request has been enqueued for this arity (Phase 10.7). Set once when the warm threshold is crossed and the request is accepted; keeps Tier-0 dispatch from re-enqueueing.

§compile_queued: AtomicBool§native_fn_ptr: AtomicPtr<()>

Finalized native function pointer, or null if not yet compiled. Calling convention: SystemV/C ABI, N ptr-sized params, one ptr-sized return.

§epoch: AtomicU64

Reclamation epoch of the published native code (0 = none). Assigned by the JIT worker when it registers the compiled module; used by code unloading to identify which JITModule backs this pointer and to track whether a frame executing this code is live at a safepoint.

§arg_profile: Mutex<Vec<u8>>

Observed argument-type bitmasks, one byte per IR parameter (Phase 10.6). OR-accumulated by JitState::record_call until the compile is queued; the JIT worker reads it to decide per-parameter specializations (JitState::arg_type_profile).

§deopt_count: AtomicU32

Entry-guard failures of the published specialized code. Crossing deopt_limit discards the specialization (see JitState::record_deopt).
