NullableStore

A very stupid type that does nothing more than store a TypeValue and a key. Is is useful to break cycles in type systems. The value of KeyType.init must equal nullvalue;

@safe pure nothrow @nogc

struct NullableStore (

T

KType = ulong

KType nullvalue = KType.init

) {

alias TypeValue = T;

alias KeyType = KType;

static immutable

auto NullValue;

bool isNull();

}
