Classes
struct	CellSpecies
	The partial densities of one cell, in any layout. More...
struct	State
	Conservative state of every cell: the flow block and the partial densities of a mixture's species. A single gas has no species columns, and every loop over them is empty. More...

Typedefs
using	StateView = Kokkos::View< rtype *[N_CONSERVATIVE]>
	Flow block [rho, rho u, rho E] per cell.
using	SpeciesLayout = Kokkos::LayoutRight
	Layout of the species block: LayoutRight keeps a cell's species contiguous (the default); LayoutLeft (CMake Mallard_SPECIES_LAYOUT_LEFT) a species' cells.
using	SpeciesView = Kokkos::View< rtype **, SpeciesLayout >
	Partial densities rho Y_k per (cell, species).

Functions
KOKKOS_INLINE_FUNCTION CellSpecies	cell_species (const SpeciesView &rhoY, const uint32_t c)
void	deep_copy (const State &dst, const State &src)
	Copy both blocks of src into dst.
template<typename ExecSpace >
void	deep_copy (const ExecSpace &exec, const State &dst, const State &src)
	Copy both blocks of src into dst, ordered on exec without a fence.

SpeciesLayout

using SpeciesLayout = Kokkos::LayoutRight

Layout of the species block: LayoutRight keeps a cell's species contiguous (the default); LayoutLeft (CMake Mallard_SPECIES_LAYOUT_LEFT) a species' cells.

SpeciesView

using SpeciesView = Kokkos::View<rtype **, SpeciesLayout>

Partial densities rho Y_k per (cell, species).

StateView

using StateView = Kokkos::View<rtype *[N_CONSERVATIVE]>

Flow block [rho, rho u, rho E] per cell.
