invalid_tape_index

template<typename ADNumberType , typename T = void>

const Types<ADNumberType>::tape_index Differentiation::AD::Numbers< ADNumberType, T >::invalid_tape_index

static

Initial value:

=
        0u

A tape index that is unusable and can be used to invalidate recording operations.
