feat: Support stable diffusion.cpp as a WasmEdge plugin

[hydai]

Summary

Motivation

WasmEdge runtime provides inference support for AI models and LLMs (large language models, such as llama3 and phi-3-mini). Stable Diffusion is a popular category that we would like to support. We would like to build a WasmEdge plugin that uses stable-diffusion.cpp as the backend and a set of WASI extensions like WASI-NN for developers to use.

Details

Objectives

The primary objectives of this project are to create a WasmEdge plugin and an SDK to use these functions with the following features:

• Support txt2img
• Support img2img
• Allow users to use Rust/C/C++ language to develop an application for using this plugin

Deliverables

Upon successful completion of this project, the following deliverables are expected:

1. A Rust language framework for WasmEdge applications to support txt2img, img2img, and most of the options listed in this table
2. A WasmEdge plugin that implements and integrates the stable diffusion features.
3. Documentation and sample applications

Appendix

• stable diffusion.cpp
• WASI-NN
• WASI-NN Rust SDK

Are we making a rust wrapper for stable diffusion.cpp?
