结构体 Sink 

pub struct Sink { /* private fields */ }

一个将数据移入空白的异步 writer。

此结构体 通常通过调用 sink 创建。 有关更多详细信息， 请参阅 sink() 的文档。

这是 std::io::Sink 的异步版本。

Trait 实现

impl AsyncWrite for Sink

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

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<(), Error>>

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<(), Error>>

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>>

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 Sink

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
