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: limit.rs
    path of file: ./repos/FnckSQL/src/execution/codegen/dql
    
    the code of the file until where you have to start completion: use crate::execution::codegen::CodeGenerator;
use crate::execution::ExecutorError;
use crate::planner::operator::limit::LimitOperator;
use mlua::Lua;

pub struct Limit {
    _id: i64,
    offset: Option<usize>,
    limit: Option<usize>,
}

impl From<(LimitOperator, i64)> for Limit {
    fn from((LimitOperator { offset, limit }, id): (LimitOperator, i64)) -> Self {
        Limit {
            offset,
            limit,
            _id: id,
        }
    }
}

impl CodeGenerator for Limit {
    fn produce(&mut self, _: &Lua, _: &mut String) -> Result<(), ExecutorError> {
        Ok(())
    
    fn consume(&mut self, _: &Lua, script: &mut String) -> Result<(), ExecutorError> {
        let Limit { offset, limit, .. } = self;

        if limit.is_some() && limit.unwrap() == 0 {
            return Ok(());
        }

        let offset_val = offset.unwrap_or(0);
        let offset_limit = offset_val + limit.unwrap_or(1) - 1;

        script.push_str(
            format!(
                r#"
                if index < {} then
                    goto continue
                end
                if index > {} then
                    break
                end
            "#,
                offset_val, offset_limit
            )
            .as_str(),
        );

        Ok(())
    }
