Abstractions over the low level apis (opengl, directx, vulkan, metal) have gotten a bit popular in recent years. I think some driving forces behind it are inconsistent support of some apis on some platforms (i.e. opengl on macos) and maybe also a desire to support some of the newer apis (Vulkan or dx12) without going all in due to their complexity/verbosity.

I've been playing with wgpu-rs, bgfx, and a couple others in the past and they work pretty well for the most part. At this point I think I'd still rather choose just Vulkan for a new project though.
