Struct IoState

pub struct IoState { /* private fields */ }

Values of this structure are returned from Connection::process_new_packets and tell the caller the current I/O state of the TLS connection.

Implementations

impl IoState

pub fn tls_bytes_to_write(&self) -> usize

How many bytes could be written by Connection::write_tls if called right now. A non-zero value implies CommonState::wants_write.

pub fn plaintext_bytes_to_read(&self) -> usize

How many plaintext bytes could be obtained via std::io::Read without further I/O.

pub fn peer_has_closed(&self) -> bool

True if the peer has sent us a close_notify alert. This is the TLS mechanism to securely half-close a TLS connection, and signifies that the peer will not send any further data on this connection.

This is also signalled via returning Ok(0) from std::io::Read, after all the received bytes have been retrieved.

Trait Implementations

impl Debug for IoState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for IoState

fn eq(&self, other: &IoState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
