Struct async_process::ChildStderr
source · [−]pub struct ChildStderr(_);Expand description
A handle to a child process’s standard error (stderr).
When a ChildStderr is dropped, the underlying handle gets closed.
Implementations
sourceimpl ChildStderr
impl ChildStderr
sourcepub async fn into_stdio(self) -> Result<Stdio>
pub async fn into_stdio(self) -> Result<Stdio>
Convert async_process::ChildStderr 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").arg("x").stderr(Stdio::piped()).spawn()?;
let stdio:Stdio = ls_child.stderr.take().unwrap().into_stdio().await?;
let mut echo_child = Command::new("echo").stdin(stdio).spawn()?;Trait Implementations
