`gpu::dispatch::Dim3`

cheatah-gpu v0.5.1-alpha — Biome Standard 0.6.3-alpha

Three-dimensional dispatch extents — the (x, y, z) triple every GPU dispatch interface takes, whether it is vkCmdDispatch(x, y, z) or Metal's MTLSize.

Also spells problem sizes and per-axis device limits (maxComputeWorkGroupCount[3]), so one type serves items, local sizes, workgroup counts, and clamps. Unused axes default to 1 — a 1-D dispatch is Dim3{items} — matching how the hardware treats a missing axis (one slice, not zero).
