Struct async_std::process::ChildStdin

pub struct ChildStdin(/* private fields */);

Available on unstable only.

A handle to a child process’s standard input (stdin).

When a ChildStdin is dropped, the underlying handle gets closed. If the child process was previously blocked on input, it becomes unblocked after dropping.

Implementations

impl ChildStdin

pub async fn into_stdio(self) -> Result<Stdio, Error>

Convert async_process::ChildStdin into std::process::Stdio.

You can use it to associate to the next process.

Examples

use async_process::Command;
use std::process::Stdio;

let mut ls_child = Command::new("ls").stdin(Stdio::piped()).spawn()?;
let stdio:Stdio = ls_child.stdin.take().unwrap().into_stdio().await?;

let mut echo_child = Command::new("echo").arg("./").stdout(stdio).spawn()?;

Trait Implementations

impl AsFd for ChildStdin

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl AsRawFd for ChildStdin

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl AsyncWrite for ChildStdin

fn poll_write( self: Pin<&mut ChildStdin>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_flush( self: Pin<&mut ChildStdin>, cx: &mut Context<'_>, ) -> Poll<Result<(), Error>>
