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: mod.rs
    path of file: ./repos/tokio/tokio/src/loom/std
    
    the code of the file until where you have to start completion: #![cfg_attr(any(not(feature = "full"), loom), allow(unused_imports, dead_code))
    
    pub(crate) fn seed() -> u64 {
        let rand_state = RandomState::new();

        let mut hasher = rand_state.build_hasher();

        // Hash some unique-ish data to generate some new state
        COUNTER.fetch_add(1, Relaxed).hash(&mut hasher);

        // Get the seed
        hasher.finish()
    }
