Please forgive my stackoverflow-like usage of github.
My initial idea would be to not modify the 'validation.By' signature but to wrap your custom rule function.
func buildCheckABC(args ...interface{}) {
return func checkAbc(value interface{}) error {
// do something with 'args' and 'value'
}
}
And then call it somewhat like
err := validation.Validate("xyz", validation.By( buildCheckABC(arg1, arg2)))
Just an idea, not tested at all.

I tried the same but it create cyclic import issue if I send the whole struct. (Possible way to send each field separately and handled the same in return func)
In my case, I need to validate a field by creating a HMAC using the other fields in the same struct and compare the same against the filed passed for validation.

I'm running into the same issue, has anyone figure out a solution for this?

Have you tried @burner-account's suggestion? It should work.

Oh that does work @qiangxue, thanks do you think its worth wile to add docs for this?

This is a typical usage of using closure to parameterize a function. But yes, it doesn't hurt to add an example to the docs.
