Random open questions from my notes

[LukasKalbertodt]

Not sure how much of this still makes sense, but I wanted to transfer everything from private notes to GitHub.

• Open Questions
  • Maybe impl Deref<Target=Handle> for ElementRef
  • Make {Element}Ref thingies a single pointer? Also make them always valid, i.e. non constructable by users.
  • Add add_vertex(pos) and the like methods to fat meshes (automatically?)
  • derive(FatMesh) to add several methods like add_vertex(position).
  • Think about abstracting over (core mesh, position) again to make passing fat meshes into algorithms easier
• Final touches
  • Rename {Element}Ref to {Element}?
  • Maybe remove derive_more dependency
  • Guard more stuff behind features
  • Go through all TODOs
  • Remove profile.release debug=true
• IO
  • Write edges and edge data
  • Think about more fat meshes? Vertex normals?
  • Make ErrorKind nicer
  • Add null sink
  • Config::into_writer should be in a trait (and then we can add wrote_to_mem)
• hsize and handles
  • Add cargo feature to use u64 as hsize
  • Add cargo feature to check for overflow in release mode too
  • Think about how to avoid using handles in wrong universes
  • Think about how to avoid using handles to already deleted things
  • Derive Handle for structs with one hsize field
• Unsorted
  • Think about indexing Prop-thingies with Into<Handle> or so
  • Think about implementing conversions between meshes + maybe a way to quickly add all faces and only fix adjacency info afterwards?
  • Add fat::EmptyMesh or implement Mem* for all core mesh types
  • Think about futures and progress bars
  • Add try_add_face which returns a result
  • Let user disable deletion to avoid storing the bitvec?
