pub fn try_clone(&self) -> Result<Self>
Create a new PipeWriter instance that shares the same underlying file description.
§Examples
use std::process::Command;
use std::io::{pipe, Read};
let (mut reader, writer) = pipe()?;
// Spawn a process that writes to stdout and stderr.
let mut peer = Command::new("bash")
    .args([
        "-c",
        "echo -n foo\n\
         echo -n bar >&2"
    ])
    .stdout(writer.try_clone()?)
    .stderr(writer)
    .spawn()?;
// Read and check the result.
let mut msg = String::new();
reader.read_to_string(&mut msg)?;
assert_eq!(&msg, "foobar");
