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: opt.rs
    path of file: ./repos/wasmtime/crates/cli-flags/src
    
    the code of the file until where you have to start completion: //! Support for parsing Wasmtime's `-O`, `-W`, etc "option groups"
//!
//! This builds up a clap-derive-like system where there's ideally a single
//! macro `wasmtime_option_group!` which is invoked per-option which enables
//! specifying options in a struct-like syntax where all other boilerplate about
//! option parsing is contained exclusively within this module.
