Struct Writer 

pub struct Writer<'a> {
    sink: &'a mut dyn PlaintextSink,
}

A structure that implements std::io::Write for writing plaintext.

Fields

sink: &'a mut dyn PlaintextSink

Implementations

impl<'a> Writer<'a>

pub(crate) fn new(sink: &'a mut dyn PlaintextSink) -> Self

Create a new Writer.

This is not an external interface. Get one of these objects from Connection::writer.

Trait Implementations

impl Write for Writer<'_>

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

Send the plaintext buf to the peer, encrypting and authenticating it. Once this function succeeds you should call Connection::write_tls which will output the corresponding TLS records.

This function buffers plaintext sent before the TLS handshake completes, and sends it as soon as it can. See ConnectionCommon::set_buffer_limit to control the size of this buffer.

If the connection previously encountered a fatal error (for example, while processing received data in Connection::process_new_packets), this returns that error, even if buf is empty.

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

This does not do any I/O, but returns the fatal error the connection previously encountered, if any.

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

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

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.

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

Attempts to write an entire buffer into this writer.

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

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

Attempts to write multiple buffers into this writer.

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

Writes a formatted string into this writer, returning any error encountered.

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
