pub struct ChildStdin { /* fields omitted */ }
A handle to a child process's standard input (stdin).
This struct is used in the stdin
field on Child
.
When an instance of ChildStdin
is dropped, the ChildStdin
's underlying
file handle will be closed. If the child process was blocked on input prior
to being dropped, it will become unblocked after dropping.
Consumes this object, returning the raw underlying file descriptor. Read more

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