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: compiler_pipeline.rs
    path of file: ./repos/gluon/src
    
    the code of the file until where you have to start completion: //! Advanced compiler pipeline which ensures that the compilation phases are run in order even if
//! not the entire compilation procedure is needed.
//!
//! Each trait in this
    
    pub fn map<F>(self, f: impl FnOnce(E) -> F) -> CompileValue<F> {
        let CompileValue {
            expr,
            core_expr,
            typ,
            metadata,
            module,
        } = self;
        CompileValue {
            expr: f(expr),
            core_expr,
            typ,
            metadata,
            module,
        }
    }
