Struct tokio::process::ChildStdin

pub struct ChildStdin { /* private fields */ }

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.
