Function repeat [src]

Returns a vector containing the same elements as the input, but repeated until the desired length is reached. For example, repeat(8, [_]u32{1, 2, 3}) will return a vector containing .{1, 2, 3, 1, 2, 3, 1, 2}.

Prototype

pub fn repeat(comptime len: usize, vec: anytype) @Vector(len, std.meta.Child(@TypeOf(vec)))

Parameters

len: usize

Source

  pub fn repeat(comptime len: usize, vec: anytype) @Vector(len, std.meta.Child(@TypeOf(vec))) {
    const Child = std.meta.Child(@TypeOf(vec));

    return @shuffle(Child, vec, undefined, iota(i32, len) % @as(@Vector(len, i32), @splat(@intCast(vectorLength(@TypeOf(vec))))));
}
