Validate struct inside struct with custom functions

[LoKKeR96]

Hi everyone, as per title I'm trying to validate structs inside another struct with custom function but none of the solutions or guidelines I have found online have worked for me. I am not sure why.

Say I have:

type MainStruct struct {
Val1 *FirstStruct
Val2 *SecondStruct
}

I want to be able to validate each struct (if not nil) in a custom function. Does anyone know how to do this please?

@LoKKeR96 in the documentation you may do so by registering as custom struct validation.
