Does this support reliable packet fragmentation? #3

Also, does it work well with Unity Android/IOS Aot? And does it support reliable ordered? Thanks for any info!

It works very well with Unity's IL2CPP/AoT because there is no native dll dependency or marshalling. I use IL2CPP exclusively for my mobile ports.

Hazel does not support fragmented messages. I am somewhat lukewarm on it because I have no personal need for that feature, and I haven't gotten any feedback about it. I added a statistic Connection.Statistics.FragmentableMessagesSent that counts messages sent over 1200 bytes and found I never did that. For everything between 1200 and 64kb, UDP will fragment unreliably which will cause a disconnect when Hazel sends a reliable message over 1200 bytes through a no-fragment connection.

Hazel also does not support reliable ordered, however because it supports reliable sending, I tend to implement ordering at the application layer. I'm less likely to add this into Hazel because I want to keep Hazel very minimal. I don't like libraries that add extra overhead for features I may or may not use. But I might be tempted to craft and include helper classes that make ordered messaging straightforward at the application layer.
