equal

auto eve::algo::equal = function_with_traits<equal_>[all_of.get_traits()]

inlineconstexpr

#include <eve/module/algo/algo/equal.hpp>

Tests wether two ranges are equal (accepts anything that zips together as a range of 2 things) By default aligns and unrolls 4 times.

namespace eve::algo
{
 
  template <zipped_range_pair Rng>
  bool equal(Rng&& rng);                                             // 1
 
  template <zipped_range_pair Rng, typename P>
  bool equal(Rng&& rng, P p);                                        // 2
 
  template<typename R1, typename R2>
  bool equal(R1&& r1, R2&& r2) requires zip_to_range<R1, R2>;        // 3
 
  template<typename R1, typename R2, typename P>
  bool equal(R1&& r1, R2&& r2, P p) requires zip_to_range<R1, R2>;  // 4
}

1. Compare both halves of zipped_range_pair for equality
2. Compare both halves of zipped_range_pair for equivalence using predicate P
3. Compare r1 and r2 that zip together to zip_range_pair for equality
4. Compare r1 and r2 that zip together to zip_range_pair for equivalence using predicate P

Note

1. and 3. will convert to common type to do equality comparison if necessary to get the same for custom predicate, use [common_type] trait on your zip.

to better understand the zip interfaces, have a look at examples/algorithms/using_existing/memcmp_... or examples/algorithms/using_existing/case_insensitive....

Parameters

• rng: zipped pair of 2 ranges to compare
• 'r1,r2- two separate components thatzipto azipped_range_pair ! *p` - binary predicate for equivelence testing.

    **Return value**
  
    bool wether any values matched the predicate
