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/ferrocarril/mruby/src/extn/stdlib
    
    the code of the file until where you have to start completion: use crate::{Mrb, MrbError};

pub mod delegate;
pub mod forwardable;
pub mod json;
pub mod monitor;
pub mod ostruct;
pub mod set;
pub mod strscan;
mod stubs;
pub mod uri;

pub fn patch(interp: &M
    
pub fn patch(interp: &Mrb) -> Result<(), MrbError> {
    stubs::patch(interp)?;
    delegate::init(interp)?;
    forwardable::init(interp)?;
    json::init(interp)?;
    monitor::init(interp)?;
    ostruct::init(interp)?;
    set::init(interp)?;
    strscan::init(interp)?;
    uri::init(interp)?;
    Ok(())
