# Troubles encountered with Rust during the making of this library
- Lack of plugins means that you have to use a build script to compile your shaders instead of inlining them directly where they are used.
- [No way to create dynamic-sized arrays on the stack](https://github.com/rust-lang/rfcs/issues/618). A lot of Vulkan functions require
passing an array of small elements (small structs or integers). Building such an array with a `Vec` can be expensive, especially
when most of the time the array only contains a single element.

- HKTs would make for a nicer API.
- Some trait implementations have an associated type that looks like `type T = (Arc<Foo>, Arc<Bar>);`. HKTs would allow this parameter to take
references to the Arcs instead, and avoid having to clone them.
