How do I implement AsyncWrite for enum?

[Faputa]

I have an enum like this:

use tokio::{io::WriteHalf, net::{tcp::OwnedWriteHalf, TcpStream}};
use tokio_rustls::server::TlsStream;

#[derive(Debug)]
pub enum TcpWriter {
    TcpWriter(OwnedWriteHalf),
    TlsTcpWriter(WriteHalf<TlsStream<TcpStream>>),
}

I want to implement AsyncWrite for it:

use tokio::io::AsyncWrite;

impl AsyncWrite for TcpWriter {
    // TODO
}

Is it possible? What should I do?

An enum like this is available as tokio_util::either::Either. You can find the source in tokio-util/src/either.rs.

Thank you very much, I'll look into it.
