Class map_indices_impl

class map_indices_impl<size, Fn> meta

template <size_t size, auto... Fn>
struct map_indices_impl { … }

Compile-time index transformer used to build shuffle/permutation tables.

Template parameters
size number of output indices; the input sequence is [0, size) .
Fn... unary callables size_t -> size_t applied right-to-left. 
// Square then negate-listed-last-applied-first: result is {0, 1, 4, 9}
 using sq = map_indices_t<4, fn_return_constant<size_t, 0>>; // identity-like example
