Function std.array.replicate

Returns an array that consists of s (which must be an input range) repeated n times. This function allocates, fills, and returns a new array. For a lazy version, refer to std.range.repeat.

Prototypes

ElementEncodingType!S[] replicate(S)(
  S s,
  size_t n
)
if (isDynamicArray!S);

ElementType!S[] replicate(S)(
  S s,
  size_t n
)
if (isInputRange!S && !isDynamicArray!S);

Example

auto a = "abc";
auto s = replicate(a, 3);

assert(s == "abcabcabc");

auto b = [1, 2, 3];
auto c = replicate(b, 3);

assert(c == [1, 2, 3, 1, 2, 3, 1, 2, 3]);

auto d = replicate(b, 0);

assert(d == []);
