Struct std::process::ChildStdin
1.0.0 · source · [−]pub struct ChildStdin { /* private fields */ }
Expand description
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.

1.20.0 · sourceimpl From<ChildStdin> for Stdio
impl From<ChildStdin> for Stdio
sourcefn from(child: ChildStdin) -> Stdio
fn from(child: ChildStdin) -> Stdio
Converts a ChildStdin
into a Stdio
.
Examples
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()) // Converted into a Stdio here
.output()
.expect("failed echo command");
// "!dlrow ,olleH" echoed to console
