Using `deno_emit` from Rust: building import graph

I'm trying to use deno_emitdeno_emit from Rust to bundle modules. I already evaluated these modules with deno_runtimedeno_runtime, is there any way to extract and use the module graph and transpiled code that was already built during evaluation? Or perhaps reuse deno_core::ModuleLoaderdeno_core::ModuleLoader for deno_graph::source::Loaderdeno_graph::source::Loader? I'm having a hard time figuring out how to use deno_emitdeno_emit and deno_graphdeno_graph from Rust, so I'm hoping there's an easier way to bundle code since I already evaluated the modules.
