Struct async_std::process::ChildStdin
source · [−]pub struct ChildStdin(_);
Expand description
A handle to a child process’s standard input (stdin).
When a ChildStdin
is dropped, the underlying handle gets clossed. If the child process was
previously blocked on input, it becomes unblocked after dropping.
Implementations
sourceimpl ChildStdin
impl ChildStdin
sourcepub async fn into_stdio(self) -> Result<Stdio, Error>
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()?;
