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: module_info_polyfill.rs
    path of file: ./repos/wasmer/lib/api/src
    
    the code of the file until where you have to start completion: //! Polyfill skeleton that traverses the whole WebAssembly module and
//! creates the corresponding import and export types.
//!
//! This shall not be needed once the JS type reflection API is available
//! for the Wasm imports and exports.
//!
//! <https://github.com/WebAssembly/js-type
    
pub fn wptype_to_type(ty: wasmparser::ValType) -> WasmResult<Type> {
    match ty {
        wasmparser::ValType::I32 => Ok(Type::I32),
        wasmparser::ValType::I64 => Ok(Type::I64),
        wasmparser::ValType::F32 => Ok(Type::F32),
        wasmparser::ValType::F64 => Ok(Type::F64),
