Random-access iterator that lazily materializes views of a collection by index.
Declared in <kernel/bitcoinkernel_wrapper.h>
template<
typename Collection,
typename ValueType,
auto GetFunc>
class Iterator;Dereferencing invokes GetFunc on the collection with the current index, returning a copy (a lightweight view), so the iterator does not hold elements.
