AliasPack

Same as an AliasSeq that does not auto expand.

You can get to the provided compile time sequence (AliasSeq) by accessing the .Unpack member. And if you want a recursive expansion there's UnpackDeep for that. Also a convenience .equals!(otherAliasPack) is provided.

template AliasPack (

T...

) {

alias Unpack = T;

enum length;

alias UnpackDeep = UnpackDeepImpl!T;

template equals(U...);

import std.meta : Alias;;

alias Head = Alias!(T[0]);

alias Head = void;

alias Tail = AliasPack!(T[1..$]);

alias Tail = AliasPack!();

}

Examples

alias P = AliasPack!(1, int, "abc");
static assert( P.equals!(1, int, "abc"));
static assert(!P.equals!(1, int, "cba"));

static assert(P.Head == 1);
static assert(P.Tail.equals!(int, "abc"));
static assert(is(P.Tail.Head == int));
static assert(P.Tail.Tail.Head == "abc");

alias PackOfPacks = AliasPack!(AliasPack!(1, int), AliasPack!(2, float), 17);
static assert(AliasPack!(PackOfPacks.UnpackDeep).equals!(1, int, 2, float, 17));
