Struct JitCodeBacking 

Source 
pub(crate) struct JitCodeBacking {
    tracker: Option<ResourceTracker>,
    _jd_guard: Arc<JitDylibGuard>,
}
Expand description

Owns JIT-compiled machine code via an ORCv2 ResourceTracker and a [JitDylibGuard].

The tracker provides per-entry code removal: dropping it calls tracker.remove() which frees this entry’s machine code. The guard keeps the owning JITDylib alive — it won’t be cleared or recycled until all guards are dropped.

This enables true per-entry eviction: removing a CompiledProgram from the resident map reclaims its machine code once all callers release their Arc<CompiledProgram> handles.

Fields§

§tracker: Option<ResourceTracker>
Available on crate feature llvm only.

The tracker that owns this entry’s machine code. Must be dropped (after remove()) BEFORE _jd_guard to ensure the JITDylib is still valid when we remove resources from it.

§_jd_guard: Arc<JitDylibGuard>
Available on crate feature llvm only.

Keeps the owning JITDylib alive. Dropped after tracker.
