Struct openssl::ssl::SslStream

pub struct SslStream<S> { /* fields omitted */ }

A TLS session over a stream.

Methods

impl<S: Read + Write> SslStream<S>

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

Like read, but returns an ssl::Error rather than an io::Error.

It is particularly useful with a nonblocking socket, where the error value will identify if OpenSSL is waiting on read or write readiness.

This corresponds to SSL_read.

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

Like write, but returns an ssl::Error rather than an io::Error.

It is particularly useful with a nonblocking socket, where the error value will identify if OpenSSL is waiting on read or write readiness.

This corresponds to SSL_write.

pub fn shutdown(&mut self) -> Result<ShutdownResult, Error>

Shuts down the session.

The shutdown process consists of two steps. The first step sends a close notify message to the peer, after which ShutdownResult::Sent is returned. The second step awaits the receipt of a close notify message from the peer, after which ShutdownResult::Received is returned.

While the connection may be closed after the first step, it is recommended to fully shut the session down. In particular, it must be fully shut down if the connection is to be used for further communication in the future.

This corresponds to SSL_shutdown.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub fn get_ref(&self) -> &S

Returns a shared reference to the underlying stream.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub fn get_mut(&mut self) -> &mut S

Returns a mutable reference to the underlying stream.

Warning

It is inadvisable to read from or write to the underlying stream as it will most likely corrupt the SSL session.

pub fn ssl(&self) -> &SslRef

Returns a shared reference to the Ssl object associated with this stream.
