Detailed Description

template<class ElementType, class Extents, class Generator>
class uni20::generated_accessor< ElementType, Extents, Generator >

Accessor that evaluates a generator at the logical index encoded by an offset.

Template Parameters

ElementType	Scalar value returned by the generator.
Extents	Mdspan extents used to decode linear offsets.
Generator	Callable accepting an index array and returning an element value.
