Apple releases C++ wrapper for Metal.

Metal-cpp is a low-overhead C++ interface for Metal that helps developers add Metal functionality to graphics apps, games, and game engines that are written in C++.

Apple Developer

Highlights:

• Drop in C++ alternative interface to the Metal Objective-C headers.
• Direct mapping of all Metal Objective-C classes, constants and enums to C++ in the MTL C++ namespace.
• No measurable overhead compared to calling Metal Objective-C headers, due to inlining of C++ function calls.
• No usage of wrapper containers that require additional allocations.
• Identical header files and function/constant/enum availability for iOS, iPadOS, macOS and tvOS.
• Backwards compatibility: All bool MTL::Device::supports...() functions check if their required selectors exist and automatically return false if not.
• String (ErrorDomain) constants are weak linked and automatically set to nullptr if not available.
