Struct tokio::process::ChildStdin
source · [−]pub struct ChildStdin { /* private fields */ }
Expand description
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
sourceimpl ChildStdin
impl ChildStdin
sourcepub fn from_std(inner: ChildStdin) -> Result<Self>
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.

sourcefn poll_write(
self: Pin<&mut Self>,

buf: &[u8]
) -> Poll<Result<usize>>
fn poll_write(
self: Pin<&mut Self>,
cx: &mut Context<'_>,
buf: &[u8]
) -> Poll<Result<usize>>
Attempt to write bytes from buf
into the object. Read more
sourcefn poll_flush(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>
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. Read more
sourcefn poll_shutdown(
self: Pin<&mut Self>,
_cx: &mut Context<'_>
) -> Poll<Result<()>>
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. Read more

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

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

implementation. Read more
