Using the Variant (Setting it's memory location)

[Era Scarecrow]

I've been working and building a struct called 'AllTypes' which 
I've come to the conclusion is already available as a variant. 
However as I look at the documentation I don't see any 
methods/constructors to use where I can specify where I want the 
data to be access from.

The data I will be accessing has dozens of different structures 
of records which I keep the formatting and types saved in an 
array. I see the problem where although variant can handle what I 
need, but I don't see a way to specify a specific memory 
range/access in order to use it.

ubyte[] buffer;

//buffer is loaded at some point with data so length > 0;
buffer.length = 2;

//0 is the offset from the buffer rather than making a range.
Variant v(buffer, int8, 0);
v = 10;
assert(buffer[0] == 10);

v = Variant(buffer, int8, 1);
v = 25;

assert(buffer[0] == 10);
assert(buffer[1] == 25);
