[go-nuts] Embedding an interface with a function type

Hi Goperhs! How you doing? Hope just fine! I'm wondering why the language allow me to write something like this: type IncFunc func(a int) int type Incrementor interface { IncFunc *// <-- THIS is allowed* IncQuantity() int } (RTR example here ) I don't get how

[go-nuts] Embedding shared libraries into gomobile archive

Hi all! I've got a golang project that uses cgo to interface with an external C library. So golang builds depend on that library's *.h and *.so files. Is there a way to tell `gomobile bind` to embed these external shared libraries into generated Android AAR or iOS Framework files? Thanks. --

[go-nuts] Embedding any (empty interface) in a struct in Go

Consider a scenario where you want to embed an error within any type of variable. This can be achieved by embedding any in a struct and it seems to be a valid syntax in Go 1.9. type WithError struct { any err error } func main() { a := WithError{ any: 5,

I've implemented a simple js sdk goplay to connect to a reverse proxy to the official go playground service at go.dev/play. Now it seems works smoothly. If you are interested in this, I'd like to share it with you: ggicci.me/goplay. On Tuesday, June 2, 2015

[go-nuts] embedding files in tests

When a file is embedded in a test file, will the file be embedded only in the test binary? The documentation says nothing about this case, but the data from go list seems to confirm that the file is only embedded in the test binary. Thanks Manlio -- You received this message because you are su

Re: [go-nuts] embedding - Access child struct elements by type casting

I'm not sure I understand the question correctly. You *can* use the variable in the switch block (i.e. in the indvidual cases). But maybe these two quotes from the spec answer your question nevertheless: Quote 1 : Each clause in a "switch" or "select" statement

Re: [go-nuts] embedding - Access child struct elements by type casting

Thanks Axel. The examples make it very clear. https://play.golang.org/p/fSLw3R_tujV So what's the differences between the implicit block around the switch statement and if statement (or loop-variables)? -- - the variables defined in the if statement's implici

Re: [go-nuts] embedding - Access child struct elements by type casting

Go does not allow declaring the same identifier in one scope twice, but there is an implicit block around the switch statement. This is the same mechanism by which loop-variables are scoped. So it is functionally equivalent to this

Re: [go-nuts] embedding - Access child struct elements by type casting

Thanks Axel. One question, how come the following would even compile? func setf(p Parenter) { switch p := p.(type) { case Child: p.Attr2 = "foo" case Child2: p.Attr3 = "foo" } } I.e., in setf(), we have two `p`s with different types, how can it be even possible with Go? -- I thought Go

As others have mentioned, the lingo is wrong (there is no inheritance in Go), but this is how you can make your specific code work as intended: https://play.golang.org/p/LVE8gFDtAM7 On Sun, Jan 14, 2018 at 3:08 PM, wrote: > Use the interface type assertion or type switch: https://tour.golang. >
