Struct async_process::ChildStdout
source · pub struct ChildStdout(_);
Expand description
A handle to a child process’s standard output (stdout).
When a ChildStdout
is dropped, the underlying handle gets closed.
Implementations§
source§impl ChildStdout
impl ChildStdout
sourcepub async fn into_stdio(self) -> Result<Stdio>
pub async fn into_stdio(self) -> Result<Stdio>
Convert async_process::ChildStdout into std::process::Stdio.
You can use it to associate to the next process.
Examples
use async_process::Command;
use std::process::Stdio;
use std::io::Read;
use futures_lite::AsyncReadExt;
let mut ls_child = Command::new("ls").stdout(Stdio::piped()).spawn()?;
let stdio:Stdio = ls_child.stdout.take().unwrap().into_stdio().await?;
let mut echo_child = Command::new("echo").stdin(stdio).stdout(Stdio::piped()).spawn()?;
let mut buf = vec![];
echo_child.stdout.take().unwrap().read(&mut buf).await;
