for_each() [2/2]

template<typename Func , auto... S>

constexpr auto kwk::for_each ( Func &&  f, shape< S... > const &  shp  )

constexpr

Simple walkthrough over all possible indexes.

Applies the given function object f to every coordinates that are valid inside the given kwk::shape shp. Coordinates are iterated in order of the optimal memory access.

Parameters

f	Function object, to be applied to a variadic list of integral coordinates. The signature of the function should be equivalent to the following: void f(std::integral auto... is);
shp	A kwk::shape used as boundaries for the coordinates

Returns

The function object f which could have been modified.
