This Rust crate provides a simple, brokerless message-queue abstraction over asynchronous
network streams. It guarantees ordered message delivery and reception, and both TCP and TLS
transports are supported.
// construct a new message
let msg = String::from("Hello world!");
-let envelope: ConnectDatagram = ConnectDatagram::new(65535, msg.into_bytes())?;
+let envelope: ConnectDatagram = ConnectDatagram::with_tag(65535, msg.into_bytes())?;
// send a message to the server
conn.writer().send(envelope).await?;
// wait for the echo-server to reply with an echo
if let Some(mut envelope) = conn.reader().next().await {
// take the message payload from the envelope
- let data: Vec<u8> = envelope.take_data().unwrap();
+ let data: Vec<u8> = envelope.data().to_vec();
// reconstruct the original message
let msg = String::from_utf8(data)?;
Connect provides a `ConnectionWriter` and `ConnectionReader` interface to concurrently send
and receive messages over a network connection. Each user-provided message is prefixed by 8
-bytes, containing a size-prefix (4 bytes), version tag (2 bytes), and recipient tag (2 bytes).
-The size-prefix and version tag are used internally to deserialize messages received from the
-network connection. The recipient tag is intended for crate users to identify the message
+bytes, containing a size-prefix (4 bytes), version field (2 bytes), and tag field (2 bytes).
+The size-prefix and version field are used internally to deserialize messages received from the
+network connection. The tag field is intended for crate users to label the message for a
recipient, although the library leaves that up to the user's discretion.
Library users must serialize their custom messages into bytes (`Vec<u8>`), prior to
gives the developer the freedom to use a serialization format of their choosing. This means that
library users can do interesting things such as:
-- Use the recipient tag to signify which serialization format was used for that message
-- Use the recipient tag to signify the type of message being sent
+- Use the tag field to signify which serialization format was used for that message
+- Use the tag field to signify the type of message being sent

+# connect tcp-client-blaster example
+
+This example program will:
+
+1. Establish a connection with a TCP server
+2. Send a number of `String` messages to the server
+3. Wait for `String` messages reply from the server
+4. Validate that the messages are received in the correct order
