Implementations

`impl PipeWriter`

fn try_clone(&self) -> Result<Self>

Creates a new PipeWriter instance that shares the same underlying file description.

Examples

# fn main() -> std::io::Result<()> {
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");

peer.wait()?;
# Ok(())
# }
