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.
