Detailed Description

template<class T>
class pixie::SplitSpan< T >

A logical contiguous sequence stored in at most two physical spans.

Empty input spans are canonicalized away. Iteration visits only non-empty physical spans in logical order. The descriptor owns no elements; its spans follow the lifetime and invalidation rules of their backing storage.

Template Parameters

T	Viewed element type, optionally const-qualified.
