Detailed Description

template<typename ITEM_TYPE, auto GENERATION_PTR>
class utrace::Ring_slot< ITEM_TYPE, GENERATION_PTR >

Ring buffer slot.

The ring buffer slot encapsulates one ring buffer item and makes sure that the item is aligned to the nearest larger power-of-two of its size.

Another purpose of this class is to abstract away the access to the sequence number of the item.

Template Parameters

ITEM_TYPE	Actual ring buffer item type.
GENERATION_PTR	Class member pointer to the member that contains the sequence number within the item. The member needs to be suitable for an atomic reference.
