Struct ChildStdin 

pub struct ChildStdin { /* private fields */ }

Async handle to the child’s standard input.

Implements AsyncWrite for sending data to the child.

Example

use asupersync::io::AsyncWriteExt;

let mut child = Command::new("cat")
    .stdin(Stdio::piped())
    .stdout(Stdio::piped())
    .spawn()?;

if let Some(mut stdin) = child.stdin() {
    stdin.write_all(b"hello\n").await?;
}

Implementations

impl ChildStdin

pub fn as_raw_fd(&self) -> RawFd

Returns the raw file descriptor.

Trait Implementations

impl AsyncWrite for ChildStdin

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

Attempt to write data from buf.

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

Attempt to flush buffered data.

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

Attempt to shutdown the writer.

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

Attempt to write data from multiple buffers (vectored I/O).

fn is_write_vectored(&self) -> bool

Returns whether this writer has efficient vectored writes.

impl Debug for ChildStdin

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