Struct rustls::ServerSession[][src]

pub struct ServerSession { /* fields omitted */ }

This represents a single TLS server session.

Send TLS-protected data to the peer using the io::Write trait implementation. Read data from the peer using the io::Read trait implementation.

Implementations

impl ServerSession[src]

pub fn new(config: &Arc<ServerConfig>) -> ServerSession

Notable traits for ServerSession

impl Read for ServerSessionimpl Write for ServerSession
[src]

Make a new ServerSession. config controls how we behave in the TLS protocol.

pub fn get_sni_hostname(&self) -> Option<&str>[src]

Retrieves the SNI hostname, if any, used to select the certificate and private key.

This returns None until some time after the client’s SNI extension value is processed during the handshake. It will never be None when the connection is ready to send or process application data, unless the client does not support SNI.

This is useful for application protocols that need to enforce that the SNI hostname matches an application layer protocol hostname. For example, HTTP/1.1 servers commonly expect the Host: header field of every request on a connection to match the hostname in the SNI extension when the client provides the SNI extension.

The SNI hostname is also used to match sessions during session resumption.

pub fn received_resumption_data(&self) -> Option<&[u8]>[src]

Application-controlled portion of the resumption ticket supplied by the client, if any.

Recovered from the prior session’s set_resumption_data. Integrity is guaranteed by rustls.

Returns Some iff a valid resumption ticket has been received from the client.

pub fn set_resumption_data(&mut self, data: &[u8])[src]

Set the resumption data to embed in future resumption tickets supplied to the client.

Defaults to the empty byte string. Must be less than 2^15 bytes to allow room for other data. Should be called while is_handshaking returns true to ensure all transmitted resumption tickets are affected.

Integrity will be assured by rustls, but the data will be visible to the client. If secrecy from the client is desired, encrypt the data separately.

pub fn reject_early_data(&mut self)[src]

Explicitly discard early data, notifying the client

Useful if invariants encoded in received_resumption_data() cannot be respected.

Must be called while is_handshaking is true.

Trait Implementations

impl Debug for ServerSession[src]

impl Read for ServerSession[src]

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

Obtain plaintext data received from the peer over this TLS connection.

If the peer closes the TLS session cleanly, this fails with an error of kind ErrorKind::ConnectionAborted once all the pending data has been read. No further data can be received on that connection, so the underlying TCP connection should closed too.

Note that support close notify varies in peer TLS libraries: many do not support it and uncleanly close the TCP connection (this might be vulnerable to truncation attacks depending on the application protocol). This means applications using rustls must both handle ErrorKind::ConnectionAborted from this function, and unexpected closure of the underlying TCP connection.

impl Session for ServerSession[src]

fn write_tls(&mut self, wr: &mut dyn Write) -> Result<usize>[src]

Writes TLS messages to wr.

impl Write for ServerSession[src]

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

Send the plaintext buf to the peer, encrypting and authenticating it. Once this function succeeds you should call write_tls which will output the corresponding TLS records.

This function buffers plaintext sent before the TLS handshake completes, and sends it as soon as it can. This buffer is of unlimited size so writing much data before it can be sent will cause excess memory usage.
