Re: How to rewrite it in Rust
#42> However, Rust has a killer feature when it comes to this sort of thing. It can call into C code with no overhead (i.e. the runtime doesn’t need to inject automatic marshalling like C#’s P/Invoke) and it can expose functions which can be consumed by C just like any other C function. As we see below, you may still need to write some code to convert from C types to something that is more ergonomic to use in Rust. But…
> As we see below, you may still need to write some code to convert from C types to something that is more ergonomic to use in Rust. But the marshaling ABI-wise is minimal. Exactly, as much as I love writing Rust code, there is nothing that is more frustrating that maintaining bindings from C to Rust. Then you'd have to create another idiomatic binding on top of it. Sure bindgen is great, but Zig's cImport and Swift'…
At some point, I figure you will always need human intervention to get actually idiomatic interop, whether it's C marshalling, JSON serialization, database persistence, etc.

#43We did a similar thing with a Scala -> Rust rewrite for the http://prisma.io query engine. By rewriting small components and integrating them into the existing project using Javas native interface, our small team of 5 developers were able to pull off this massive rewrite in just under a year. The resulting code base is rearchitected in a few very important ways, but mostly follows the same structure. And because we k…
It'd be great to hear from your experience about using Javas native interface. AFAIK, using native call can have a performance impact: https://en.wikipedia.org/wiki/Java_Native_Interface#Performa...
I guess the plan what to make native is pretty important. Maybe you want to disclose more details about that?
