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: io.rs
    path of file: ./repos/polars/crates/polars-pipe/src/executors/sinks
    
    the code of the file until where you have to start completion: use std::fs;
use std::fs::File;
use std::path::{Path, PathBuf};
use std::sync::atomic::{AtomicUsize, Ordering};
use std::time::{Duration, SystemTime};

use crossbeam_channel::{bounded, unbounded, Receiver, Sender};
use polars_core::error::ErrString;
use polars_core::prelude::*;
use polars_core::utils::arrow::temporal_conversions::SECONDS_IN_DAY;
use polars_io::prelude::*;

    
fn clean_after_delay(time: Option<SystemTime>, secs: u64, path: &Path) {
    if let Some(time) = time {
        let modified_since = SystemTime::now().duration_since(time).unwrap().as_secs();
        if modified_since > secs {
            // This can be fallible if another thread removes this.
            // That is fine.
            let _ = std::fs::remove_dir_all(path);
        }
    } else {
        polars_warn!("could not modified time on this platform")
    }
}
