I solved this by using Wasm. Your outer application shell calls into Wasm business logic, only the inner logic needs to get recompiled, the outer app shell doesn't even need to restart.

I don’t think I can use wasm with simd or syscalls, which is the bulk of my work.

I haven't used SIMD in Rust (or Wasm). Syscalls can be passed into the Wasm env.

Could definitely be more effort than it is worth just to speed up compilation.

How is this different than dynamically linking the business logic library?

[sitkack]

Very similar, but Wasm has additional safety properties and affordances. I am trying to get away from dynamic libs as an app extension mechanism. It is especially nice when application extension is open to end users, they won't be able to crash your application shell.
