Go functions dot notation

Question

I want to build this:

finalResult, err := Function1(whatever type)
    .Function2(whatever type)
    .Function3(whatever type)

Something similar to promises in javascript but not necessarily the same concepts. Or similar to nested methods in Java. I just pretend avoid more code for the same tasks.

I don't want to do this :

result, err := new(Function1(whatever type)) //or *Function1(whatever type)
if err != nil {...}
result1, err := result.Function2(whatever type)
if err != nil {...}
finalResult, err := result1.Function3(whatever type)
if err != nil {...}

I've been trying with several options with structs and interfaces but I can't get any result.

My apology if I have a mistake in my grammar. I'm not still so good with my skill English.

Thanks,

David
