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.

Trait Implementations

impl AsRawFd for ChildStdin

pub fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl AsyncWrite for ChildStdin

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

Attempt to write bytes from buf into the object.

pub 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.

pub 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.

pub 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.

pub fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for ChildStdin

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

Formats the value using the given formatter.
