Struct std::process::ChildStdin

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.

impl From<ChildStdin> for Stdio[src]1.20.0

fn from(child: ChildStdin) -> Stdio[src]

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
