Hi all,
I've read a lot about escape analysis in golang, but still couldn't find an
answer to this question
here is the sample <https://play.golang.org/p/GWotXWY0ksC>:
package main
type IMeta interface {
Index() int
}
type Builder struct {
buf []byte
meta IMeta
}
func main() {
var buffer [512]byte
b := Builder{buffer[:0], nil}
if b.meta != nil {
b.meta.Index()
}
}
escape analyzer says:
.\main.go:15:21: buffer escapes to heap
.\main.go:13:6: moved to heap: buffer
<autogenerated>:1:0: leaking param: .this
Could anyone please clarify why local buffer escapes here?
Thx in advance
