Alias `std.meta.Repeat`

Creates an AliasSeq which repeats a type or an AliasSeq exactly n times.


						
				alias Repeat(ulong n, TList...)
				 = AliasSeq!();

Example

alias ImInt0 = Repeat!(0, int);
static assert(is(ImInt0 == AliasSeq!()));

alias ImInt1 = Repeat!(1, immutable(int));
static assert(is(ImInt1 == AliasSeq!(immutable(int))));

alias Real3 = Repeat!(3, real);
static assert(is(Real3 == AliasSeq!(real, real, real)));

alias Real12 = Repeat!(4, Real3);
static assert(is(Real12 == AliasSeq!(real, real, real, real, real, real,
    real, real, real, real, real, real)));

alias Composite = AliasSeq!(uint, int);
alias Composite2 = Repeat!(2, Composite);
static assert(is(Composite2 == AliasSeq!(uint, int, uint, int)));

Example

auto staticArray(T, size_t n)(Repeat!(n, T) elems)
{
    T[n] a = [elems];
    return a;
}

auto a = staticArray!(long, 3)(3, 1, 4);
assert(is(typeof(a) == long[3]));
writeln(a); // [3, 1, 4]
