In my case this mesh "pre-processing" may be a bit time consuming, when mesh size begins to grow, that's why I was wondering if the information could be obtained directly from gmsh...

After that functions like [ cell_edges, cell_verts ] = prob.mesh.get_ev_c(elem); [ cell_faces, cell_edges, cell_verts ] = prob.mesh.get_fev_c(elem); for a 2D or a 3D mesh respectively, are processed "efficiently". (Note that all the other topological queries are available.)
