Struct tokio::process::ChildStderr

pub struct ChildStderr { /* private fields */ }

The standard error stream for spawned children.

This type implements the AsyncRead trait to read data from the stderr handle of a child process asynchronously.

Implementations

impl ChildStderr

pub fn from_std(inner: ChildStderr) -> Result<Self>

Creates an asynchronous ChildStderr from a synchronous one.

Errors

This method may fail if an error is encountered when setting the pipe to non-blocking mode, or when registering the pipe with the runtime’s IO driver.

Trait Implementations

impl AsFd for ChildStderr

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

impl AsRawFd for ChildStderr

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl AsyncRead for ChildStderr

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_> ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl Debug for ChildStderr

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

Formats the value using the given formatter.

impl TryInto<Stdio> for ChildStderr

type Error = Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<Stdio, Self::Error>

Performs the conversion.
