transform_keep_if

auto eve::algo::transform_keep_if = function_with_traits<transform_keep_if_>[no_traits]

inlineconstexpr

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

Defined in Header

#include <eve/module/algo.hpp>

Conditionally copies values that pass a predicate to the beginning of the range, transforming them in the process. Values past the returned sentinel are to be considered garbage.

Note

If the scalar operation is cheap enough, ::keep_if + views::map might be slightly faster.

See ::transform_copy_if and ::keep_if for more details.

Callable Signatures

{
  template<relaxed_range Rng, typename Func>
  auto transform_keep_if(Rng&& rng, Func func) -> unaligned_iterator_t<Rng>
}

Parameters

• rng: Range to modify
• func: Function that takes elements from rng as SIMD registers and returns a pair of:
  • the transformed values
  • a logical mask

Return value

Iterator past the last written element.
