@Jenztsch@FizzyOrange it would be nice if rust had a feature like inline macros for this kind of behavior just for reducing duplications when you don’t need to capture values as part of a closure.
@varsock rust has very good code generation for C (and sometimes C++ as well) headers via bindgen (https://github.com/rust-lang/rust-bindgen). This allows you to potentially make minimal changes to the code without having to refactor to use a new protocol on the legacy side, and has faster performance (benchmark to confirm), since there’s no serialization/deserialization step. See https://doc.rust-lang.org/nomicon/ffi.html for how this is done manually.
@darkregn Checkout @jonhoo’s channel. He has many videos doing deep dives into how rust works, and several case studies of existing crates and how they work. They are excellent resources for learning rust.

Eg
fn foo() -\> Vec\<i32\> { let mut out = Vec::new(); macro! bar(i: i32) { out.push(i); } for i in 1..10 { bar!(i); } out }
