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: renamer.rs
    path of file: ./repos/ruff/crates/ruff_linter/src
    
    the code of the file until where you have to start completion: //! Code modification struct to support symbol renaming within a scope.

    /// 1. Determine the scope in which the rename should occur. This is typically the scope passed
    ///    in by the caller. However, if a symbol is `nonlocal` or `global`, then the rename needs
    ///    to occur in the scope in which the symbol is declared. For example, attempting to rena
