1.0.0[][src]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.

Trait Implementations

impl Write for ChildStdin[src]

fn write_vectored(&mut self, bufs: &[IoVec]) -> Result<usize>[src]

🔬 This is a nightly-only experimental API. (iovec #58452)

Like write, except that it writes from a slice of buffers. Read more

fn write_all(&mut self, buf: &[u8]) -> Result<()>[src]

Attempts to write an entire buffer into this writer. Read more

fn write_fmt(&mut self, fmt: Arguments) -> Result<()>[src]

Writes a formatted string into this writer, returning any error encountered. Read more

Important traits for &'_ mut I
fn by_ref(&mut self) -> &mut Self where
    Self: Sized

Creates a "by reference" adaptor for this instance of Write. Read more

impl From<ChildStdin> for Stdio

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

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")
    .expect("failed reverse command");

let _echo = Command::new("echo")
    .arg("Hello, world!")
    .stdout(reverse.stdin.unwrap()) // Converted into a Stdio here
    .expect("failed echo command");

// "!dlrow ,olleH" echoed to consoleRun
