Expand description

The heap allocation Node type

The Node type is never ACTUALLY created or used directly, but instead is used as a “superset” of its children to ensure that the alignment and necessary size are respected at the time of allocation. Allocation is ALWAYS done as a Node<T>, meaning that conversions from an active type to a Recycle type are always sound.
