In D2, I can treat a uint as an array of ubytes by doing this:
uint num = /+...whatever...+/;
ubyte[] = cast(ubyte[4])num;
How do I do that in D1?
IIRC, D1 requires an explicit slice operator to convert from a
static-array
to a slice/dynamic-array, so I tried this:
ubyte[] = (cast(ubyte[4])num)[];
But I get the error:
Error: e2ir: cannot cast num of type uint to type ubyte[4u]
We can learn from C here :)
ubyte[] x = (cast(ubyte *)&num)[0..4];
Essentially, pointers are *always* castable to one another, and do not go
through any translations. Go to pointer-land, then back, and all your
casts shall work. It's how C++'s reinterpret_cast works.
