结构体 WriteEarlyData 

pub struct WriteEarlyData<'a> { /* private fields */ }

Stub that implements io::Write 并 dispatches 到 write_early_data。

实现

impl<'a> WriteEarlyData<'a>

pub fn bytes_left(&self) -> usize

可发送的字节数量 once this reaches zero.

Trait 实现

impl Write for WriteEarlyData<'_>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes 缓冲区 into this writer, returning how many bytes were written. 更多信息

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination. 更多信息

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes 从 一个 slice of buffers. 更多信息

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation. 更多信息

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts 到 write an entire 缓冲区 into this writer. 更多信息

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts 到 write multiple buffers into this writer. 更多信息

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes 一个 formatted string into this writer, returning any error encountered. 更多信息

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates 一个 “by reference” adapter 用于 this instance of Write. 更多信息
