PipeWriter in std::io - Rust (original) (raw)
pub struct PipeWriter(/* private fields */);🔬This is a nightly-only experimental API. (anonymous_pipe #127154)
Expand description
Write end of an anonymous pipe.
🔬This is a nightly-only experimental API. (anonymous_pipe #127154)
Create a new PipeWriter instance that shares the same underlying file description.
§Examples
#![feature(anonymous_pipe)]
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");
