结构体 Writer 

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

A structure that implements std::io::Write 用于 writing 明文.

Trait 实现

impl Write for Writer<'_>

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

发送明文 buf 到 the peer, encrypting 并 authenticating it. Once 此函数 succeeds you should call Connection::write_tls which will output the corresponding TLS records.

This function buffers 明文 sent before the TLS handshake completes, 并 sends it as soon as it can. ，请参见ConnectionCommon::set_buffer_limit 到 control the size of this 缓冲区.

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

Like write, except that it writes from a slice of buffers. 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 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
