Wraps together all the types needed for a graphics backend.

Each backend module, such as OpenGL or Metal, will implement this trait with its own concrete types.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
