# LandauIdx

Integer type used to index entries in the `DMPLEX` Landau collision-operator data structures, such as the COO matrix workspaces and the `P4estVertexMaps` reduced-quadrature maps

## Note

`LandauIdx` is a `PetscInt`; it is named separately so the device-side data structures used by the Landau collision operator can be sized independently from the rest of PETSc if needed.
