You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: build.rs
    path of file: ./repos/pants/src/rust/engine/protos
    
    the code of the file until where you have to start completion: // Copyright 2018 Pants project contributors (see CONT
    
fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut config = Config::new();
    config.bytes(["."]);
    config.disable_comments([
        // the comments on these fields contain invalid HTML/Markdown (e.g. "clientip:<ip address of
        // client>" outside of a code segment)
        "google.rpc.ResourceInfo.owner",
        "google.rpc.QuotaFailure.Violation.subject",
    ]);

    tonic_build::configure()
    .build_client(true)
    .build_server(true)
    .compile_with_config(
      config,
