+1. individual API libraries like ash, d3d12-rs, metal-rs - for the lowest hard-core level available to Rust
+2. gfx-hal for lowest portable level
+3. Rendy for helping to solve the rough corners of gfx-hal
+4. wgpu-rs for the lowest safe level
+5. Engines like ggez or Amethyst for the highest level

 >CG has been discontinued, and is no longer supported or actively worked on by Nvidia. Nvidia recommends that all users switch to a combination of GLSL and HLSL, or a newer library such as nvFX (on github). This is because it was too difficult to maintain feature-compatibility between GLSL and HLSL. https://gamedev.stackexchange.com/questions/4234/what-are-the-pros-and-cons-of-hlsl-vs-glsl-vs-cg/4333#4333
