0.4.7

  • Bugfix release (#85).

0.4.6

  • Send RST frame if the window of a dropped stream is 0 and it is in state SendClosed (#84).

0.4.5

  • Removed bytes (#77) and thiserror (#78) dependencies.
  • Removed implicit BufWriter creation (#77). Client code that depends on this (undocumented) behaviour needs to wrap the socket in a BufWriter before passing it to Connection::new.
  • Added Connection::is_closed flag (#80) to immediately return Ok(None) from Connection::next_stream after Err(_) or Ok(None) have been returned previously.

0.4.4

  • Control and stream command channels are now closed and drained immediately on error. This is done to prevent client code from submitting further close or other commands which will never be acted upon since the API contract of Connection::next_stream is that after None or an Err(_) is returned it must not be called again.

0.4.3

  • Updates nohash-hasher dependency to v0.2.0.

0.4.2

  • A new configuration option lazy_open (off by default) has been added and inbound streams are now acknowledged (#73). If lazy_open is set to true we will not immediately send an initial WindowUpdate frame but instead just set the SYN flag on the first outbound Data frame. See Configuration::set_lazy_open for details.

0.4.1

  • Log connection reset errors on debug level (#72).

0.4.0

  • Hide StreamId::new and update dependencies.

0.3.0

Update to use and work with async/await:

  • Config::set_max_pending_frames has been removed. Internal back-pressure made the setting unnecessary. As another consequence the error ConnectionError::TooManyPendingFrames has been removed.
  • Connection no longer has methods to open a new stream or to close the connection. Instead a separate handle type Control has been added which allows these operations concurrently to the connection itself.
  • In Yamux 0.2.x every StreamHandle I/O operation would drive the Connection. Now, the only way the Connection makes progress is through its next_stream method which must be called continuously. For convenience a function into_stream has been added which turns the Connection into a futures::stream::Stream impl, invoking next_stream in its poll_next method.
  • StreamHandle has been renamed to Stream and its methods credit and state have been removed.
  • Stream also implements futures::stream::Stream and produces Packets.
  • ConnectionError::StreamNotFound has been removed. Incoming frames for unknown streams are answered with a RESET frame, unless they finish the stream.
  • DecodeError has been renamed to FrameDecodeError and DecodeError::Type corresponds to FramedDecodeError::Header which handles not just unknown frame type errors, but more. Hence a new error HeaderDecodeError has been added for those error cases.

0.2.2

  • Updated dependencies (#56).

0.2.1

  • Bugfix release (pull request #54).

0.2.0

  • Added max_pending_frames setting to Config. A Connection buffers outgoing frames up to this limit (see pull request #51).
  • Added ConnectionError::TooManyPendingFrames if max_pending_frames has been reached.
  • Changed error types of Connection::close and Connection::flush from std::io::Error to yamux::ConnectionError.
  • Removed Connection::shutdown method which was deprecated since version 0.1.8.

0.1.9

  • Add read_after_close setting to Config which defaults to true to match the behaviour of previous versions. Setting read_after_close to false will cause stream reads to return with Ok(0) as soon as the connection is closed, preventing them from reading data from their buffer.

0.1.8

  • Mark Connection::shutdown as deprecated (#44).

0.1.7

  • Bugfix release (#36).
  • Support for half-closed streams (#38).
  • Avoids redundant RESET frames (#37).
  • Better test coverage (#40, #42).

0.1.6

  • Bugfix release (pull requests #34 and #35).

0.1.5

  • Bugfix release (pull request #33).

0.1.4

  • Bugfix release (pull requests #30 and #31).

0.1.3

  • Bugfix release (pull requests #27 and #28).

0.1.2

  • Bugfix release. See pull request #26 for details.

0.1.1

  • Forward Stream::poll to the newly added Connection::poll method which accepts self as a shared reference. See pull request #24 for details.

0.1

  • Initial release.
