Struct openssl::ssl::SslStream

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

A TLS session over a stream.

Implementations

impl<S: Read + Write> SslStream<S>

pub unsafe fn from_raw_parts(ssl: *mut SSL, stream: S) -> Self

Constructs an SslStream from a pointer to the underlying OpenSSL SSL struct.

This is useful if the handshake has already been completed elsewhere.

Safety

The caller must ensure the pointer is valid.

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.

pub fn get_shutdown(&mut self) -> ShutdownState

Returns the session's shutdown state.

This corresponds to SSL_get_shutdown.

pub fn set_shutdown(&mut self, state: ShutdownState)

Sets the session's shutdown state.

This can be used to tell OpenSSL that the session should be cached even if a full two-way shutdown was not completed.

This corresponds to SSL_set_shutdown.

impl<S> SslStream<S>

pub fn get_ref(&self) -> &S

Returns a shared reference to the underlying stream.

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.

Trait Implementations

    S: Debug, 

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

Formats the value using the given formatter.

impl<S> Drop for SslStream<S>

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_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

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, appending them to 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 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 writer, 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_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

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

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

Attempts to write multiple buffers into this writer.

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.
