Description

The Tensor type — a labeled box of numbers, plus all its supporting types.

This is the framework's universal data carrier. A Tensor knows what numbers it holds (dtype, shape, strides_bytes), where they live (device, storage of one of four StorageKinds), and what they represent (Semantic — image, audio, tessellated tile, encoded video, quantization payload, or preprocessing residue). The Tensor's storage is typically zero-copy across processors via the unified IOMMU; this file defines the TensorBuffer abstraction that hides the per-storage-kind details.

Headline types in this file:

• Tensor — the user-facing struct.
• TensorBuffer (alias Storage) — the storage handle with map_fn for read/write.
• Mapping — a scoped read/write window into a buffer (RAII-unmap on destruction).
• Plane — per-plane info for composite formats (NV12 = Y + UV, I420 = Y + U + V).
• Semantic — discriminated union of "what this tensor means" (image, audio, tess, etc.).
• TensorRouteMeta — routing metadata used by multi-output models.
• Device / DeviceType — where the tensor lives (CPU/CVU/MLA/APU).
