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: windows.rs
    path of file: ./repos/wasmtime/crates/wasi-common/src/tokio/sched
    
    the code of the file until where you have to start completion: use crate::sync::sched::windows::poll_oneoff_;
use crate::tokio::block_on_dummy_executor;
use crate::{file::WasiFile, sched::Poll, Error};

pub async 
    
pub async fn poll_oneoff<'a>(poll: &mut Poll<'a>) -> Result<(), Error> {
    // Tokio doesn't provide us the AsyncFd primitive on Windows, so instead
    // we use the blocking poll_oneoff implementation from the wasi_common::sync impl.
    // We provide a function specific to this impl's WasiFile types for downcasting
    // to a RawHandle.
    block_on_dummy_executor(move || poll_oneoff_(poll, wasi_file_is_stdin))
}
