for reading plaintext.

fn read(&mut self, buf: &mut [u8]) -> Result<usize>
Obtain plaintext data received from the peer over this TLS connection.
If the peer closes the TLS session cleanly, this returns Ok(0)
once all
the pending data has been read. No further data can be received on that
connection, so the underlying TCP connection should be half-closed too.
If the peer closes the TLS session uncleanly (a TCP EOF without sending a
close_notify
alert) this function returns a std::io::Error
of type
ErrorKind::UnexpectedEof
once any pending data has been read.
Note that support for close_notify
varies in peer TLS libraries: many do not
support it and uncleanly close the TCP connection (this might be
vulnerable to truncation attacks depending on the application protocol).
This means applications using rustls must both handle EOF
from this function, and unexpected EOF of the underlying TCP connection.
If there are no bytes to read, this returns Err(ErrorKind::WouldBlock.into())
.
You may learn the number of bytes available at any time by inspecting
the return of Connection::process_new_packets
.
