std::flat_m...lue_compare(3)   C++ Standard Libary  std::flat_m...lue_compare(3)

NAME
     std::flat_map::value_compare - std::flat_map::value_compare

Synopsis
	class value_compare;  (since C++23)

	std::flat_map::value_compare  is a function object that compares objects
     of type
	std::flat_map::const_reference (a  pair  of  references  to  the  stored
     key/value) by
	comparing the first components (i.e. keys) of the passed pairs.

Member objects
	Member name    Definition
	comp	(private)    the    comparison	  function    object   of   type
     std::flat_map::key_compare
		       (exposition-only member object*)

Member functions
	constructor   constructs value_compare object
	(private)     (public member function)
	operator()    compares two values of type value_type
		      (public member function)

     std::flat_map<Key,T,Compare,KeyContainer,MappedContainer>::value_com-
     pare::value_compare

	private:			 (exposition only*)
	value_compare( key_compare c );

	Initializes the underlying instance of the comparator comp to c.

Parameters
	c - a comparator to assign

     std::flat_map<Key,T,Compare,KeyContainer,MappedContainer>::value_com-
     pare::operator()

	bool operator()( const const_reference& lhs, const const_reference&  rhs
     ) const;

	Compares lhs.first and rhs.first by calling the stored comparator comp.

Parameters
	lhs, rhs - values to compare

Return value
	comp(lhs.first, rhs.first)

Exceptions
	May throw implementation-defined exceptions.
