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: data_value.rs
    path of file: ./repos/wasmtime/cranelift/codegen/src
    
    the code of the file until where you have to start completion: //! This module gives users to instantiate values that Cranelift understands. These values are used,
//! for example, during interpretation and for wrapping immediates.
