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: options.rs
    path of file: ./repos/tools/crates/rome_analyze/src
    
    the code of the file until where you have to start completion: use crate::{Rule, RuleKey};
use std::any::{Any, TypeId};
use std::collections::HashMap;
use std::fmt::Debug;
use std::path::PathBuf;

/// A convenient new type data structure t
    
    pub fn value<O: 'static>(&self) -> &O {
        let (type_id, value) = &self.0;
        let current_id = TypeId::of::<O>();
        debug_assert_eq!(type_id, &current_id);
        // SAFETY: the code should fail when asserting the types.
        // If the code throws an error here, it means that the developer didn't test
        // the rule with the options
        value.downcast_ref::<O>().unwrap()
    }
