…ogram) Adds a new metal/ driver module mirroring the existing cuda/ structure. - Add Metal300 to Backend enum in backend.d - Add metal/package.d with version(OSX) gate - Add metal/device.d wrapping MTLDevice queries - Add metal/buffer.d with typed MetalBuffer!T and storage modes - Add metal/queue.d for command queue and compute dispatch - Add metal/program.d for loading .metallib files All implementations are stubbed; extern(Objective-C) wiring via Inochi2D/metal-d will follow once LDC compiler backend is ready.

There is a bunch of compiler work that needs to be before this |

Sure, will continue, actually, I am adding this pr in my proposal and submitting the proposal for the idea DCompute Metal Backend |

This adds an initial skeleton for a Metal compute driver, following the
same structure as the existing
dcompute.driver.cudamodule.What this adds:
Metal300variant to theBackendenum inbackend.dmetal/package.d— module entry point (version(OSX) gated)metal/device.d—MetalDevicestruct wrappingMTLDevicemetal/buffer.d—MetalBuffer!Ttyped GPU buffer with storage modesmetal/queue.d—MetalQueuefor command submission and kernel dispatchmetal/program.d—.metallibfile loading viaMTLLibraryAll implementations are stubbed out with TODO comments — the actual
extern(Objective-C)calls will be wired up using theInochi2D/metal-dbindings once the LDC compiler backend (targetMetal.cpp) is in place.
This is part of my GSoC 2026 proposal for the DCompute Metal Backend project.
I'd appreciate any early feedback on the structure and API design.
