http3 - when closing, http3.Server.Serve returns quic.ErrServerClosed instead of http.ErrServerClosed about quic-go HOT 4 CLOSED

Is that incorrect? You can have a closed QUIC server, while the HTTP/3 server is still running.

from quic-go.

what is a "QUIC server" when working at HTTP/3 api level ? Do we need to know about such 'quic' stuff at this level ?
The http3 package tries to reproduce the same API as the net/http package.

With net/http, when we use ListenAndServeTLS or just ServeTLS and the call ends, it means the server stopped. As per the documentation:

ServeTLS always returns a non-nil error. After Shutdown or Close, the returned error is ErrServerClosed.
source: https://pkg.go.dev/net/http#Server.ServeTLS

So when http3.Server.Serve(...) ends, if the returned error is quic.ErrServerClosed what is the meaning of this ?

If we have existing code that use net/http and check for http.ErrServerClosed, when we switch or add http/3 we must add a special case to check for quic.ErrServerClosed which is confusing (which is what we're currently doing now).

Should we replace the error if s.closed == true?

Should we replace the error if s.closed == true?

no that's the only place where it is correct.

other return paths should be changed.
