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: recent_files.rs
    path of file: ./repos/vim-clap/crates/maple_core/src/stdio_server/provider/impls
    
    the code of the file until where you have to start completion: use crate::datastore::RECENT_FILES_IN_MEMORY;
use crate::stdio_server::provider::hooks::CachedPreviewImpl;
use crate::stdio_server::provider::{BaseArgs, ClapProvider, Context, ProviderResult as Result};
use parking_lot::Mutex;
use paths::AbsPathBuf;
use printer::Printer;
use serde_json::json;
use std::sync::Arc;
use types::{ClapItem, MatchedItem, RankCalculator, Score};

#[derive(Debug, Clone)]
pub struct RecentFilesProvider {
    args: BaseArgs,
    printer: Printer,
    lines: Arc<Mutex<Vec<MatchedItem>>>,
}

impl RecentFilesProvider {
    pub 
    
    async fn on_initialize(&mut self, ctx: &mut Context) -> Result<()> {
        if self.args.query.is_none() {
            let preview_size = if ctx.env.preview_enabled {
                Some(ctx.preview_size().await?)
            } else {
                None
            };

            let update_info =
                self.clone()
                    .process_query(ctx.cwd.clone(), "".into(), preview_size, 1)?;

            ctx.vim.exec("clap#picker#update", update_info)?;
        } else {
            ctx.handle_base_args(&self.args).await?;
        }

        Ok(())
    }
