@ -13,6 +13,12 @@ Here is the current list of planned features. All items are sorted in approximat
* Add runtime type safety to uniform bindings (and maybe compile time)
* Inject layout set/bindings into shader source so they don't need to be defined in-shader. Specify set / binding indices in resource providers?
* Pull as much logic as possible from wgpu_renderer into a "render orchestrator" struct/trait
* Docs
* Add doc comments to code
* Add tutorials
* Add feature docs
* Add "template" projects
* Add ```#![deny(warnings, missing_docs)]``` to ensure future contributions meet style/doc standards
* Error Handling
* Custom error type?
* Remove as many panics / unwraps as possible
