Detailed Description

template<typename Discretization, typename Layout, typename Prescribed, typename... Fields>
class serif::model::backend::mfem::detail::StateCoefficients< Discretization, Layout, Prescribed, utils::dependencies::KeyList< Fields... > >

Borrow an owning state's fields for one synchronous equation evaluation.

Note

MFEM requires mutable pointers to construct its vector views, but these wrappers are only exposed through const coefficient views. Keep this adapter alive until graph evaluation returns. Recreate it for each call so copies and moves of StellarState never leave persistent self-references.
