Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Returns an ImmSet containing the values after the n-th element of the current ImmSet

public function skip(
  int $n,
): ImmSet<Tv>;

The returned ImmSet will always be a proper subset of the current ImmSet.

n is 1-based. So the first element is 1, the second 2, etc.

Parameters​

  • int $n - The last element to be skipped; the $n+1 element will be the first one in the returned ImmSet.

Returns​

  • ImmSet<Tv> - An ImmSet that is a proper subset of the current ImmSet containing values after the specified n-th element.

Examples​

See Set::skip for usage examples.
