How to use

Declare a partial struct with the [NoParamlessCtor] attribute

Example:

[NoParamlessCtor]
public ref partial struct RefCtor(ref PrimaryCtor value)
{
    public ref PrimaryCtor Value = ref value;
}

Usecases

  • Structs that will have an invalid state if new()-ed. Note that it is still possible for the end-user to declare default(SomeStruct).
