When the frontend closes the connection, it will trigger the connection.receive_datagram() method once

[BiagioFesta]

receive_datagram awaits for receiving the next datagram for the connection.

If the connection is closed during the await, then the async function will returns but with an error Err (instead of the datagram).

This is expected. And how Rust idiomatically handles errors (i.e., Result).

Surely, I need to improve documentation. For now, I limited to the essential for publishing the first version of the library

[redoriental]

My frontend closes the 'webtransport', and it takes a long 30 seconds for the backend to detect that the 'connection' has been closed.

[BiagioFesta]

The transport layer of this library currently sets a timeout of 10 seconds.

It means that by using the Connection of this library, the connection will be detected as closed (Timed-Out) in the worst case.

Worst-case means: your front-end interrupts the connection without a "graceful shutdown". For instance, by closing the UDP socket without sending a proper quic-CLOSE frame.

If your front-end properly signals the end of connection, the connection will ends immediately as soon as the udp packet arrives on the endpoint.

[redoriental]

I understand what you mean. This is also due to the underlying limitations of 'WebTransport,' as it lacks a built-in heartbeat mechanism like WebSocket. Consequently, it requires an active close action to initiate the closure.

[redoriental]

I believe that future 'WebTransport' implementations will include a heartbeat mechanism.

[BiagioFesta]

Yes. I am already working on transport configurations in order to:

• Allow settings the connection timeout.
• Allow configuring a transparent PING mechanism (this can be done by leveraging the underlying QUIC protocol), in order to keep alive the connection in case of no message exchanged for a long period.

[BiagioFesta]

Unfortunately, this requires time.

I am working hard on this, but it is more a personal project for now and it takes time :)

[redoriental]

Don't worry, I believe that in the future, there will be a large number of developers collaborating with you, including myself. However, I am currently attending university, making it difficult for me to fully dedicate myself to this project.

How is the progress?

[BiagioFesta]

New release is out v0.1.2

It includes:

• Transport settings for keep_alive PING.
• Transport settings for timeout.
• New SessionRequest to access HTTP request and decide whether accept or reject

I am closing this issue.
