Detailed Description

template<std::size_t I, typename Inner>
class Aleph::CA::Field_Slice_Rule< I, Inner >

Adaptor: apply a mono-field rule to field I, leave the other fields unchanged.

Lets the user reuse any existing RuleLike (Game of Life, outer-totalistic, continuous, lookup, ...) on a single channel of a multi-field lattice without touching the other channels. The inner rule sees only field I's current value and field I's neighbours.

Template Parameters

I	index of the targeted field.
Inner	mono-field rule type.

Pure-form invocation.

Template Parameters

FieldsTuple lattice's std::tuple<Fields...>.

Parameters

[in]	cur	current per-field values.
[in]	nb	per-field neighbour views.

Returns: tuple where field I is replaced by inner(cur, nb) and the other fields keep their current values.
