结构体 ChildStdin 

pub struct ChildStdin { /* private fields */ }

已派生子进程的标准输入流。

该类型实现了 AsyncWrite trait，用于向子进程的 stdin 句柄异步写入数据。

实现

impl ChildStdin

pub fn into_owned_handle(self) -> Result<OwnedHandle>

转换为 OwnedHandle。

impl ChildStdin

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

从一个同步的 ChildStdin 创建一个异步的 ChildStdin。

Errors

若在将管道设置为非阻塞模式，或将管道注册到运行时的 IO driver 时发生错误， 此方法可能会失败。

Trait 实现

impl AsHandle for ChildStdin

fn as_handle(&self) -> BorrowedHandle<'_>

Borrows the handle. 更多信息

impl AsRawHandle for ChildStdin

fn as_raw_handle(&self) -> RawHandle

Extracts the raw handle. 更多信息

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. 更多信息

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. 更多信息

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. 更多信息

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. 更多信息

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation. 更多信息

impl Debug for ChildStdin

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

使用给定的格式化器格式化此值。 更多信息

impl TryInto<Stdio> for ChildStdin

type Error = Error

转换出错时返回的类型。

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

执行转换。
