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: incoming.rs
    path of file: ./repos/hyper/src/body
    
    the code of the file until where you have to start completion: use std::fmt;
#[cfg(all(feature = "http1", any(feature = "client", feature = "server")))]
use std::future::Future;
use std::pin::Pin;
use std::task::{Context, Poll};

use bytes::Bytes;
#[cfg(all(feature = "http1", any(feature = "client", feature = "server")))]
use futures_channel::{mpsc, oneshot};
#[cfg(all(
    any(feature = "http1", feature = "http2"),
    any(feature = "cli
    
    fn channel_wanter() {
        let (mut tx, mut rx) =
            Incoming::new_channel(DecodedLength::CHUNKED, /*wanter = */ true);

        let mut tx_ready = tokio_test::task::spawn(tx.ready());
        let mut rx_data = tokio_test::task::spawn(rx.frame());

        assert!(
            tx_ready.poll().is_pending(),
            "tx isn't ready before rx has been polled"
        );

        assert!(rx_data.poll().is_pending(), "poll rx.data");
        assert!(tx_ready.is_woken(), "rx poll wakes tx");

        assert!(
            tx_ready.poll().is_ready(),
            "tx is ready after rx has been polled"
        );
    }
