Crate oxiproto_codegen 

oxiproto-codegen — Generate plain Rust source code from a FileDescriptorSet.

This crate walks a prost_types::FileDescriptorSet and emits plain Rust structs and enums — no prost derive, no gRPC stubs, no validators.

Quick start

use prost_types::FileDescriptorSet;

let fds: FileDescriptorSet = /* parse your .proto */ Default::default();
let rust_src = oxiproto_codegen::generate(&fds).expect("codegen failed");
println!("{rust_src}");
