Update notes

Version 0.14 modifies the connect() behaviour to perform a non-blocking connections instead. It is recommended to use this non-blocking mode in order to get the best scalability and performance in your application. If you need to perform a similar blocking connection as before (version 0.13), you can call to connect_sync().

Note also that the previous NetEvent::Connect has been renamed to NetEvent::Accepted. The current NetEvent::Connect behaves as a new event to deal with the new non-blocking connections. See NetEvent docs for more info.

Release 0.13.3

• Fixed a bad internal assert.

Release 0.13.2

• Added Endpoint::from_listener() that allows to send datagrams from listeners in non connection-oriented protocols (see the API docs).
• Removed 'static restriction in the NodeListener::for_each() callback. Now, you can pass references to the callback.
• Faster compilation. Reduced some dependencies.
• Faster NodeHandler clone and less memory usage in each instance.

Release 0.13.1

• Added NodeListener::enqueue().

Release 0.13.0

• Updated NodeListener::for_each to works fully synchronous. Send trait of the event callback parameter has been removed to works fine with objects like Rc Cell or references. This function no longer returns a NodeTask.
• New method NodeListener::for_each_async has been added to support the previous behaviour of for_each.
• Added Debug to NodeEvent.

Release 0.12.2

• Reduced WebSocket latency.

Release 0.12.1

• WebSocket now can returns when send correctly a SendStatus::MaxPacketSizeExceeded instead of ResourceNotFound if the packet size is exceeded.
• UDP has increases the packet size when send. Now more bytes per packet can be sent if the OS let it.
• Exported some adapter constants dependent.
• Transport::max_message_size() now represents the teorical maximum size (see its related docs).

Release 0.12.0

• Node concept: NodeHandler and NodeListener.
• Non-mutable and shared network operations.
• Removed AdapterEvent. Now, the only network event is NetEvent that has been modified to contains a reference to the data instead of an allocated vector.
• Removed Network entity that has been substituted by NetworkController to handle connect/listen/remove/send and NetworkProcessor to handle the input events.
• Remamed EventQueueto EventReceiver.
• Minor API additions.
• Now UDP never generates disconnection events.
• Increased performance:
  • Latency reduced in arround 66%.
  • Zero-copy message.

Update notes

Version 0.12 comes with important API changes (changelog) in order to reach zero-copy write/read goal. For a soft transition, you can use NodeListener::enqueue() (see docs).

Release 0.11.1

• Reduce the bandwidth of FramedTcp transport using variadic encoding instead of constant padding.

Release 0.11.0

• Implemented Serialize/Deserialize for Transport.
• Implemented Serialize/Deserialize for RemoteAddr.
• Changed Url to String in RemoteAddr.
• Changed RemoteAddr variant from SocketAddr to Socket.
• Changed RemoteAddr variant from Url to Str.
• Increase the ToRemoteAddr support for many types.
• Returned value of Netowork::remove() as boolean. Rationale: Removing a connected connection could return None in the previous version of remove if just a disconnection happen. The user probably will use .unwrap() on it adding a potential bug. Changing from Option<()> to bool avoid this usage.
• Added RegisterId of the listener which generates the connection in AdapterEvent::Added and NetEvent::Connection events.

Release 0.10.2

• Added try_receive() to EventQueue for non-blocking event read.
• tests and benchmarks running with any number of features enabled.

Release 0.10.1

• Transport by features: tcp, udp, websocket.

Release 0.10.0

• Renamed Transport::Tcp as Transport::FramedTcp. WARNING: If previously you was using Transport::Tcp you probably want to use now Transport::FramedTcp (that behaves the same).
• Added Transport::Tcp that has no encoding layer. Now Transport::Tcp is purely TCP.
• Renamed Transport::max_payload() to Transport::max_message_size().
• Added Endpoint into AdapterEvent.
• Fixed ResourceId compilation in 32-bits.
• Reverted inner tuple position of Network::split() in version 0.8. First Network then EventQueue, as an user would expect.

Update notes

If you comming from 0.9.4 o less, note that Transport::Tcp has been renamed to Transport::FramedTcp to be more according to its behaviour. See more here.

Release 0.9.4

• Fixed a TCP encoding issue.
• Fixed a Websocket issue that could imply to lost a message just after being accepted.
• Added burst integration test with order check.

Release 0.9.0

• Removed serialization. Rationale: The serialization inside message-io was merely a shortcut, than in most of the cases reduced the power of the user by save 2-3 lines of their code. The serialization should be handle by the user for several reasons:
  • The user could want to decide send the message in base of the serialized data size. (e.g. chosing a diffenrent transports if the serialized size exceeds the max packet size)
  • The user could want to perform some action over raw data.
  • The user could make a gateway without needed to deserialize to serialize again.
  • Or simply, there is no need to serialize in some cases.
• Network::remove_resource() to Network::resource().
• Exposed AdapterEvent.
• Added Network::split_and_map().
• Added Transport::max_payload().
• Exposed encoding module.
• Fixed message_size test for big messages.

• Fixed issue in send methods where sometimes data is lost.
• Fixed lost fragmented UDP. Before this change, a huge UDP message could be sent without respect the MTU size, now it panics.
