transform_keep_if

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.
