ehang-io/nps-mux

A net connection multiplexing implementation based on golang

nps-mux's Issues

Remove encoding.binary's Read()/Write()

Binary.Read and binary.Write use reflection and are slow
All the stream data split or combination are using it in netpackager.go
Maybe we need to do it by hand

Remove Conn interface calls

Cost of calls via interfaces, in mux.go
Maybe we should call tcp or kcp connection directly

能否给你个example帮助用户理解使用mux

没有详细的文档很难理解，能否给你个example帮助用户理解使用mux？

Support data encryption

Support data encryption

Remove pointer in map

GC will check all the pointers in map
We use it in map.go
Maybe we should use uintptr instead of pointer
sync map instead of map and RWmutex, atomic value provides Len method, range a list and delete outside

文档是否能详细些？

从nps源码过来的，文档上的usage真心看不懂呀
