HH\Lib\Vec\slice

Returns a new vec containing the subsequence of the given Traversable determined by the offset and length

namespace HH\Lib\Vec;

function slice<Tv>(
  Container<Tv> $container,
  int $offset,
  ?int $length = NULL,
): vec<Tv>;

If no length is given or it exceeds the upper bound of the Traversable, the vec will contain every element after the offset.

• To take only the first $n elements, see Vec\take().
• To drop the first $n elements, see Vec\drop().

Time complexity: O(n), where n is the size of the slice Space complexity: O(n), where n is the size of the slice

Parameters

• Container<Tv>$container
• int $offset
• ?int $length = NULL

Returns

• vec<Tv>

Examples

$vector = vec[1, 2, 3, 4, 5, 6, 7];
$sliced_vector = Vec\slice($vector, 3);
\print_r($sliced_vector);

$sliced_vector2 = Vec\slice($vector, 2, 3);
\print_r($sliced_vector2);
