For anyone interested in the Vulkan end of things, I recommend this: https://hoj-senna.github.io/ashen-aetna/

What is nice to see that with Rust's linearity, cleaning resources once they become unused can be cleared quite easily by implementing a custom drop function. The challenge remains though that to know what order you have to do it requires consultation of the Vulkan specification. Though even for this you can enable Vulkan validation layers which actually give quite clear idea what you are doing wrong.
