There is no claim because that is not how Go interfaces work - if you implement it, you are it - that being said, I wouldn’t use Read() with UDPConn - I would use one of the packet/msg reader methods instead.
Read() is a pass through to fd.Read() so it will be implementation dependent, but posix should be that only a single packet is returned. Since UDP is packet oriented, anything else would be unusable, since the packet size forms the boundaries. see http://developerweb.net/viewtopic.php?id=2952 The buffer size controls the size of the OS kernel buffer assigned to the socket - nothing to do with streaming reads. > On May 12, 2019, at 7:20 PM, Dan Kortschak <d...@kortschak.io> wrote: > > bump? > > On Thu, 2019-05-09 at 16:23 +0930, Dan Kortschak wrote: >> The Conn and UDPConn Read methods look like io.Reader Read methods, >> but >> there is no explicit claim that Conn is an io.Reader.
