std::indire...ry_predicate(3) C++ Standard Libarystd::indire...ry_predicate(3)

NAME
       std::indirect_unary_predicate - std::indirect_unary_predicate

Synopsis
	  Defined in header <iterator>
	  template<class F, class I>

	  concept indirect_unary_predicate =
	  std::indirectly_readable<I> &&
	  std::copy_constructible<F> &&				(since C++20)
	  std::predicate<F&, std::iter_value_t<I>&> &&
	  std::predicate<F&, std::iter_reference_t<I>> &&

	  std::predicate<F&, std::iter_common_reference_t<I>>;

	  The  concept indirect_unary_predicate	specifies requirements for al-
       gorithms	that call
	  unary	predicates as their arguments. The key difference between this
       concept and
	  std::predicate is that it is applied to the type that	I  references,
       rather than I
	  itself.

	 Semantic requirements

	  F  and I model indirect_unary_predicate only if all concepts it sub-
       sumes are modeled.
