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: lib.rs
    path of file: ./repos/rules_rust/examples/crate_universe/multi_package/sub_pkgs/pkg_c/src
    
    the code of the file until where you have to start completion: use md5::{Digest, Md5};

pub fn hash(bytes: impl A
    
pub fn hash(bytes: impl AsRef<[u8]>) -> Vec<u8> {
    // create a Md5 hasher instance
    let mut hasher = Md5::new();

    // process input message
    hasher.update(bytes);

    // acquire hash digest in the form of GenericArray,
    // which in this case is equivalent to [u8; 16]
    let result = hasher.finalize();
    result[..].into()
}
