问题
I'm planning on using the rust-protobuf library. I've written a bash script that builds everything (including my code) and builds the .proto files I have into .rs files. The way the documentation tells me to proceed is to specifically just do:
mod foo;
for each of the .rs files generated. I'm hoping that my users can just drop in new .proto files into a directory, run the build script, and my code will take care of including all of the Rust implementations of the compiled .proto files.
I know Rust doesn't really support reflection, so is there some way I can essentially "determine all the .rs generated files in a directory and use them in my code" (in a TLDR statement).

You could write a Cargo build script which would scan your directory and generate a Rust file that looks like:
mod file1;
mod file2;
//etc
You can then include this file in your library with the include! macro.
