Move semantics in C++ permit classes that are expensive
1. Why does C++ introduce move semantics anyway? What problems is it going
to solve?
2. How come Golang, C (Without ++) don’t have that move semantics yet? Will
they need the move soon?

Thank you Alex for your quick reply. I figured it out. Using Interfaces is
the right way to solve this.

So I'm going thru some of the Github issues, I'm wondering what will become
of these packages that are frozen in the stdlib:
- log/syslog (Implements logging facilities for *nix operating systems)
- net/smtp (Implements RFC 5321)
- net/rpc (Implements remote procedure calls for Go-Only p
This is what interfaces are for.
You have:
type GetKeyer interface {
GetKey1() string
GetKey2() string
}
Then to use it: https://play.golang.org/p/rvLsWCIBuxe
You still have to implement GetKey1 and GetKey2 on each struct, but you can
access them through a common interface without knowin
Gotcha :)
Thanks for the info, guess i will have to find a way around it then. At least i
now know there is no real way to do what i wanted so that close this door :)

Nope, not ATM. Go only works with gcc, even the dlls are made with gcc.
There is a issue on that and it seems like there is some progress but it
isn't clear when it will be
usable. https://github.com/golang/go/issues/20982
Also note that even if Go uses msvc, you would still have issues freeing
Hi,
I have a use case where there are two different versions of struct. The
problem is when the model is retrieved from database, it can be of either
version. Both structs have same getters implemented.
This is what the code looks like.
type structA {
Key1 string
Key2string
}

Hi,
I just had to move my GO environment from Linux to Windows 10. I set up
everything as simple as possible (GOROOT = C:\go, GOPATH =
%USERPROFILE%\go) to test the installation.
For an IDE I use vscode. When trying to see all referrers of a struct type
vscode only shows references within the
Thank you!
I think at this point it is very clear that this problem is due to some
weird alternative normal of my computer. D:
I will found another time to test it on another OS.

Well it is kinda reoated as im in this mass because of go :)
Anyway, is there anyway to use cgo with msvc? I actually run the cgo command
from msvc cmd assuming the c part will be compiled with msvc.
In addition as far as i know you can actually do that with visual studio if you

Memory allocated by one C/C++ runtime must and can only be freed through
the same runtime. This is not a Go/cgo problem, this is normal C/C++
behavior.
So by mixing gcc and msvc there are at least 2 C/C++ runtimes. Even mixing
different compiler versions might cause issues.

cool. if the granularity and the info open census provides is sufficient
for your use case that’s the right way.
go tool trace is for analyzing interaction between go runtime and the
application.

Hey,
in the end I've used opencensus which has the same features as go's spans,
but it's designed for distributed tracing. I already have multiple backend
support, which supports more advanced filtering options than
chrome://tracings's catapult viewer.

Hey Jake,
First if all thanks for the willing to help.
Cgo is the built-in tool in go of building c libraries (see:
https://golang.org/cmd/cgo/)
What I basically do is that I have a go code, which i build into c library
(dll), i.e, i insert the go code onto the cgo mechine then get .h and .dll
Looks like you are on windows. I have worked a lot with windows, C/C++ and
go, but never actually built a go dll. But, since no one else has picked
this up, maybe I can help.
1. I'm not sure what "the cgo" library means here? Do you have this:
cpp<->go(dll)<->c(cgo)? Or something else.
2. Ho
GoCQLX is a general purpose extensions to golang's Cassandra driver gocql.

That is an excellent example. Thanks!
