I need to figure out if a reflect.Value that is a function (Func) has a
receiver (i.e. it is a method) or if the Func is just a plain function with
no receiver in its signature.
Here's what I came up (which does appear to solve the question in the
limited cases I've tested)... but I'm wondering if there is a faster and/or
guaranteed reliable approach that doesn't feel quite so hacky with the
string comparison:
import (
"runtime"
"reflect"
...
)
...
func getFunctionName(fun reflect.Value) string {
return runtime.FuncForPC(fun.Pointer()).Name()
}
func main() {
isMethod := getFunctionName(v) == "reflect.methodValueCall"
...
}
Is there a better way? Thanks!
