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  
}  

@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 If you plan to refactor the architecture to convert things into microservices, grpc is also a solid way to go.

@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.

@varsock @Timely_Jellyfish_2077 out of curiosity, why use grpc in lieu of ffi?
