Struct tokio::process::ChildStdin

pub struct ChildStdin { /* fields omitted */ }

This is supported on crate feature process only.

The standard input stream for spawned children.

This type implements the AsyncWrite trait to pass data to the stdin handle of handle of a child process asynchronously.

Implementations

impl ChildStdin

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

Creates an asynchronous ChildStdin 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 AsRawFd for ChildStdin

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl AsyncWrite for ChildStdin

fn poll_write(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &[u8]
) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(
    self: Pin<&mut Self>,
    _cx: &mut Context<'_>
) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

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

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for ChildStdin

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

Formats the value using the given formatter.

impl TryInto<Stdio> for ChildStdin

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
