Functions
std::string_view	serif::solver::preconditioner::backend::mfem::sparse_direct_backend () noexcept
	The sparse LU backend compiled into this library (Meson option sparse_direct): "accelerate", "umfpack" or "none".
bool	serif::solver::preconditioner::backend::mfem::sparse_direct_available () noexcept
	True when SparseDirect can be prepared on this machine; with "none", or Accelerate before macOS 15.5, it cannot.
std::expected< Inverse, Failure >	serif::solver::preconditioner::backend::mfem::try_sparse_direct_inverse (std::shared_ptr< const ::mfem::SparseMatrix > matrix, const strategies::inverse::SparseDirect &options={}, SparseDirectCache *cache=nullptr)
	Factor a finalized square sparse matrix with a pivoted sparse LU; every application is one exact solve.
