[][src]Struct openssl::ssl::SslStreamBuilder

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

A partially constructed SslStream, useful for unusual handshakes.


impl<S> SslStreamBuilder<S> where
    S: Read + Write

pub fn new(ssl: Ssl, stream: S) -> Self[src]

Begin creating an SslStream atop stream

pub fn stateless(&mut self) -> Result<bool, ErrorStack>[src]

Perform a stateless server-side handshake

Requires that cookie generation and verification callbacks were set on the SSL context.

Returns Ok(true) if a complete ClientHello containing a valid cookie was read, in which case the handshake should be continued via accept. If a HelloRetryRequest containing a fresh cookie was transmitted, Ok(false) is returned instead. If the handshake cannot proceed at all, Err is returned.

This corresponds to SSL_stateless

pub fn set_connect_state(&mut self)[src]

Configure as an outgoing stream from a client.

This corresponds to SSL_set_connect_state.

pub fn set_accept_state(&mut self)[src]

Configure as an incoming stream to a server.

This corresponds to SSL_set_accept_state.

pub fn connect(self) -> Result<SslStream<S>, HandshakeError<S>>[src]

See Ssl::connect

pub fn accept(self) -> Result<SslStream<S>, HandshakeError<S>>[src]

See Ssl::accept

pub fn handshake(self) -> Result<SslStream<S>, HandshakeError<S>>[src]

Initiates the handshake.

This will fail if set_accept_state or set_connect_state was not called first.

This corresponds to SSL_do_handshake.

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

Read application data transmitted by a client before handshake completion.

Useful for reducing latency, but vulnerable to replay attacks. Call set_accept_state first.

Returns Ok(0) if all early data has been read.

Requires OpenSSL 1.1.1 or newer.

This corresponds to SSL_read_early_data.

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

Send data to the server without blocking on handshake completion.

Useful for reducing latency, but vulnerable to replay attacks. Call set_connect_state first.

Requires OpenSSL 1.1.1 or newer.

This corresponds to SSL_write_early_data.

impl<S> SslStreamBuilder<S>[src]

pub fn get_ref(&self) -> &S[src]

Returns a shared reference to the underlying stream.

pub fn get_mut(&mut self) -> &mut S[src]

Returns a mutable reference to the underlying stream.


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[src]

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

pub fn set_dtls_mtu_size(&mut self, mtu_size: usize)[src]

Set the DTLS MTU size.

It will be ignored if the value is smaller than the minimum packet size the DTLS protocol requires.


This function panics if the given mtu size can't be represented in a positive c_long range
