any_of

eve::algo::any_of = function_with_traits<any_of_>[default_simple_algo_traits]

inlineconstexpr

#include <eve/algo/any_of.hpp>

a SIMD version of std::any_of

Tests if any of the elements in the range match the predicate. by default aligns and unrolls 4 times.

Alternative Header

#include <eve/algo.hpp>

Callable Signatures

namespace eve::algo
{
  template <eve::algo::relaxed_range Rng, typename P>
  bool any_of(Rng&& rng, P p);
}

Parameters

• rng: Relaxed input range to process
• 'p': Predicate

Return value

true if p returns true for at least one element in the range, false otherwise. Returns false if the range is empty.
