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: mod.rs
    path of file: ./repos/vector/src/transforms/lua/v2
    
    the code of the file until where you have to start completion: use std::{path::PathBuf, sync::Arc, time::Duration};

use serde_with::serde_as;
use snafu::{ResultExt, Snafu};
use vector_lib::codecs::MetricTagValues;
use vector_lib::configurable::configurable_component;
pub use vector_lib::event
    
    async fn lua_drop_event() {
        run_transform(
            r#"
            version = "2"
            hooks.process = """function (event, emit)
                -- emit nothing
            end
            """
            "#,
            |tx, _out| async move {
                let event = LogEvent::default().into();
                tx.send(event).await.unwrap();

                // "run_transform" will assert that the output stream is empty
            },
        )
        .await;
    }
