The reason why my old code worked was because it used the
default arguments and I wasn't actually calling the constructor
I defined. When I removed the default arguments in the
constructor and tried case 2 it obviously didn't work.
Am I understanding correctly? Thanks
You're right about case 1 and case 2, and partially correct about
case 3. Structs don't actually have default constructors. They
have default *initializers*. In other words, s = S() is the same
as s = S.init. See item #4 in the documentation for struct
destructors [1]:
"If the ParameterList is empty, the struct instance is default
initialized."
So yes, your constructor is not being called.
