HH\ImmVector::skipWhile

Returns an ImmVector containing the values of the current ImmVector starting after and including the first value that produces false when passed to the specified callback

public function skipWhile(
  (function(Tv): bool) $fn,
): ImmVector<Tv>;

That is, skips the continuous prefix of values in the current ImmVector for which the specified callback returns true.

The returned ImmVector will always be a subset (but not necessarily a proper subset) of the current ImmVector.

Parameters

• (function(Tv): bool) $fn - The callback used to determine the starting element for the returned ImmVector.

Returns

• ImmVector<Tv> - An ImmVector that is a subset of the current ImmVector starting with the value for which the callback first returns false.

Examples
