pub struct ChildStdout { /* fields omitted */ }A handle to a child process's standard output (stdout).
This struct is used in the stdout field on Child.
When an instance of ChildStdout is dropped, the ChildStdout's
underlying file handle will be closed.

Converts a ChildStdout into a Stdio
ChildStdout will be converted to Stdio using Stdio::from under the hood.
use std::process::{Command, Stdio};
let hello = Command::new("echo")
.arg("Hello, world!")
.stdout(Stdio::piped())
.spawn()
.expect("failed echo command");
let reverse = Command::new("rev")
.stdin(hello.stdout.unwrap())
.output()
.expect("failed reverse command");
assert_eq!(reverse.stdout, b"!dlrow ,olleH\n");Run
