Initialising a Constructor with an Undef value

General Usage

Hi, I have two Struts where one struct requires and object of the other as one of it’s fields. I am wondering how to initialise with an undef value of it. Here is an example

mutable struct Casualty
  id::Int
  pos::Tuple{Int,Int,Float64}
  trauma::Int
  awaiting_rescue::Bool
end

mutable struct Rescuer
  id::Int
  pos::Tupe{Int,Int,Float64}
  casualty_in_rescue::Casualty
  casualties_rescued::Vector{Casualty}
end

rescuer_x = Rescuer(1, (75,75,160.1), undef, Casualty[])

I am wondering what to add instead of undef (which is ofcourse incorrect), where it will represent something similar to NaN value (which cannot be added cause its Float type)

how about this as your default nonevent

const NoCasualty = Casualty(0,(0,0,0.0),0,false)
