std::indire...ce_relation(3)  C++ Standard Libary std::indire...ce_relation(3)

NAME
       std::indirect_equivalence_relation - std::indirect_equivalence_relation

Synopsis
	  Defined in header <iterator>
	  template<class F, class I1, class I2 = I1>

	  concept indirect_equivalence_relation	=
	  std::indirectly_readable<I1> &&
	  std::indirectly_readable<I2> &&
	  std::copy_constructible<F> &&
	  std::equivalence_relation<F&,	std::iter_value_t<I1>&,
	  std::iter_value_t<I2>&> &&
	  std::equivalence_relation<F&,		       std::iter_value_t<I1>&,
       (since C++20)
	  std::iter_reference_t<I2>> &&
	  std::equivalence_relation<F&,	std::iter_reference_t<I1>,
	  std::iter_value_t<I2>&> &&
	  std::equivalence_relation<F&,	std::iter_reference_t<I1>,
	  std::iter_reference_t<I2>> &&

	  std::equivalence_relation<F&,	std::iter_common_reference_t<I1>,
	  std::iter_common_reference_t<I2>>;

	  The concept indirect_equivalence_relation specifies requirements for
       algorithms that
	  call equivalence relations as	their arguments.  The  key  difference
       between this
	  concept  and	std::equivalence_relation is that it is	applied	to the
       types that I1 and
	  I2 references, rather	than I1	and I2 themselves.

	 Semantic requirements

	  F, I1, and I2	model indirect_equivalence_relation only if  all  con-
       cepts it	subsumes
	  are modeled.
