Re: [go-nuts] Why sort.IsSorted implemented with decrement?

@Rob, honestly to me they look the same: func IsSorted(data Interface) bool { n := data.Len() for i := n - 1; i > 0; i-- { if data.Less(i, i-1) { return false } } return true } func IsSortedForward(data sort.Interface) bool { n := data.Len() f

Re: [go-nuts] Reflection: Constructing a struct type that satisfies an interface

What I want, in the end, is to send a gRPC request based on an ASCII or JSON representation of a protobuf, receive a response and display it. Essentially, if you take grpc_cli tool present in the repo of C implementation of gRPC, I would like to implement its "call" functionality. Even though try

[go-nuts] Re: Golang and WebAssembly

Yes, WebAssembly would be really nice replacement for gopherjs, especially for game development. Go already reached realtime garbage collection using native runtime, so theoretically we can make smooth games with 60 FPS. But gopherjs transpiles Go into JavaScript, which adds additional overhead
