Struct openssl::ssl::SslStream

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

A stream wrapper which handles SSL encryption for an underlying stream.

Methods

impl<S: Read + Write> SslStream<S>

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

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

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

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

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

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

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.

impl<S> SslStream<S>

fn get_ref(&self) -> &S

Returns a reference to the underlying stream.

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.

fn ssl(&self) -> &SslRef

Returns the OpenSSL Ssl object associated with this stream.

Trait Implementations

impl<S> Debug for SslStream<S> where S: Debug

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<S: Read + Write> Read for SslStream<S>

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

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

Read the exact number of bytes required to fill buf.

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

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl<S: Read + Write> Write for SslStream<S>

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

Write a buffer into this object, returning how many bytes were written.

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

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

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

Creates a "by reference" adaptor for this instance of Write.
