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: wasi.rs
    path of file: ./repos/wasmer/examples
    
    the code of the file until where you have to start completion: //! Running a WASI compiled WebAssembly module with Wasmer.
//!
//! This example illustrates how to run WASI modules with
//! Wasmer.
//!
//! If you need more manual contr
    
fn main() -> Result<(), Box<dyn std::error::Error>> {
    let wasm_path = concat!(
        env!("CARGO_MANIFEST_DIR"),
        "/tests/wasi-wast/wasi/unstable/hello.wasm"
    );
    // Let's declare the Wasm module with the text representation.
    let wasm_bytes = std::fs::read(wasm_path)?;

    // Create a Store.
    let mut store = Store::default();

    println!("Compiling module...");
    // Let's compile the Wasm module.
    let module = Module::new(&store, wasm_bytes)?;

    let (stdout_tx, mut stdout_rx) = Pipe::channel();

    // Run the module.
    WasiEnv::builder("hello")
        // .args(&["world"])
        // .env("KEY", "Value")
        .stdout(Box::new(stdout_tx))
        .run_with_store(module, &mut store)?;

    eprintln!("Run complete - reading output");

    let mut buf = String::new();
    stdout_rx.read_to_string(&mut buf).unwrap();

    eprintln!("Output: {buf}");

    Ok(())
