Detailed Description

template<size_t T_pos, size_t T_end, int T_step>
struct codi::CompileTimeLoop< T_pos, T_end, T_step >

Compile time loop evaluation.

step is added to pos until end is reached.

Be careful if step not -1 or 1, the end position needs to be reached directly.

Example:

int a[10];
 
// Via lambda:
CompileTimeLoop<0,10,1>::eval([&] (auto i) { a[i.value] = i.value; });
 
// Via functor:
struct SetEntry {
 
  int* vec;
  template<size_t pos>
  void operator()(std::integral_constant<size_t, pos>, Type& v, Derivative const& d) {
    vec[pos] = pos;
  }
};
CompileTimeLoop<0,10,1>::eval(SetEntry{a});

Called range is: [pos, end)

Template Parameters

T_pos	Start value for the loop.
T_end	End value for the loop.
T_step	Step value for increment or decrement.
