Struct rbatis_core::runtime::process::ChildStderr

pub struct ChildStderr(_);

A handle to a child process’s standard error (stderr).

When a ChildStderr is dropped, the underlying handle gets closed.

Implementations

impl ChildStderr

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

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

impl AsyncRead for ChildStderr

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

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    bufs: &mut [IoSliceMut<'_>]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl Debug for ChildStderr

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
