Struct openssl::ssl::SslStream

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

A TLS session over a stream.

Implementations

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.

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

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> Drop for SslStream<S>

fn drop(&mut self)

Executes the destructor for this type.

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.

pub fn read_vectored(
    &mut self,
    bufs: &mut [IoSliceMut<'_>]
) -> Result<usize, Error>

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

pub 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.

pub 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.

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

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

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

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

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

Creates a “by reference” adaptor for this instance of Read.

pub fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

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

Creates an adaptor which will chain this stream with another.

pub 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.

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

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

pub 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.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

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

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