https://github.com/golang/go/blob/master/src/reflect/type.go#L315

is  this equal func generate by compiler, so where can i find the code generate this func?

what is the rule for compare two object of same struct?

Yes, or by `reflect`.

From what I can tell:

https://github.com/golang/go/blob/75e16f5127eb6affb4b473c93565a8d29a802e51/src/cmd/compile/internal/gc/alg.go#L454

It's in the spec: https://golang.org/ref/spec#Comparison_operators

> Struct values are comparable if all their fields are comparable. Two struct values are equal if their corresponding non-blank fields are equal.
