Using an Arena/ECS style library to describe parent/child relationship amongst children

• fltk-rs

  31 1,508 9.4 Rust

  Rust bindings for the FLTK GUI library.

  

I'm working on implementing a Drag and Drop system in my fltk-rs app, and in order to do so need some way for each draggable parent widget to "know" about the nodes in a droppable widget. Having access to a graph structure becomes even more important when we consider that their might be droppable widgets within droppable widgets, and that some droppable widgets might also be draggable widgets (see this example made with react-beautiful-dnd example).

  A naive attempt at getting an Entity Sytem working backed by a generational arena (slotmap) and an AnyMap

Aha! Looks like rebo, who made that post, uses the same name on github and has a Entity System example! https://github.com/rebo/entity_system

• vec-tree

  A safe tree using an arena allocator that allows deletion without suffering from the ABA problem by using generational indices. https://docs.rs/vec-tree/0.1.0/vec_tree/

Hmm looks like this example involves some dependencies to crate versions which have been yanked, and would require some substanial redesign to get working. List crate looks promising, however! https://github.com/ArnaudValensi/vec-tree
