Tweaking null propagation easily

[brgrz]

Is there an easy way to change how null propagation works?

1. If we wanted to throw an exception when null reference encountered? There are lots of various Ignore methods, similarly I wish there were Required methods or maybe an ThrowIfNull argument to be passed in
2. If null encountered, use a provided value (I know atm it uses default or null value)

Hello @brgrz
Do you want to prevent null leaking from Source to Destination?

From this case:

2. If null encountered, use a provided value (I know atm it uses default or null value)

Maybe it will help you Mapping with condition

@brgrz If you go out something like this?

I think it can be done )

TypeAdapterConfig<Source,Destination>
.NewConfig()
.Map(x=>x.Value, y=>y.Value).IfNullDefault(42)
.Map(x=>x.SomeValue, y=>y.SomeValue).IfNullAction(x=> GetThrow(x))

@brgrz Can you describe in more detail the conditions in which you want to use this:

1. Should this only apply to reference types, or also to nullable ValueType?
2. Should this work for types declared in Nullable Enable Context or only for other types?
