Local image generation backend for Blazen using diffusion-rs.
This crate wraps the diffusion-rs pure-Rust Stable Diffusion inference
engine to provide fully local, offline image generation with no API keys
required.
When used through blazen-llm with the diffusion feature flag, this
crate's [DiffusionProvider] will implement blazen_llm::ImageGeneration.
Feature flags
| Feature | Description |

Links the actual diffusion-rs runtime (CPU) |
cuda |
NVIDIA CUDA GPU acceleration |
metal |
Apple Silicon GPU acceleration (Metal) |
Without the engine feature the crate compiles (options struct + stub
provider) but cannot actually run image generation. This keeps workspace
builds fast when the heavy native dependencies are not needed.
