From d98a83e5fd169c25755d8e109f690e51c306176e Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 30 Mar 2026 10:06:11 +0000 Subject: [PATCH 01/16] feat: implement rusty_ai SDK ecosystem with 13 crates and 10 examples Complete Cargo workspace with unified AI SDK architecture: Core crates: - rusty_ai: traits (LanguageModel, EmbeddingModel, Provider, Tool, Middleware), typed errors, streaming (futures::Stream), structured output, routing - rusty_middleware: retry with backoff, logging, caching, middleware chain - rusty_ui_stream: SSE + NDJSON encoders, versioned UI protocol - rusty_testing: mock models/providers, stream assertions Cloud providers: - rusty_openai_compatible: generic OpenAI-compatible API adapter - rusty_chatgpt: OpenAI ChatGPT (GPT-4o, o3-mini) - rusty_claude: Anthropic Messages API (Sonnet, Opus, Haiku) - rusty_gemini: Google Gemini API with multimodal support - rusty_ollama: local Ollama server with NDJSON streaming Local/platform runtimes (bridge-based, first-class): - rusty_gemini_nano: Android Prompt API with session support - rusty_foundationmodels: Apple Foundation Models - rusty_phi_silica: Windows NPU Phi Silica - rusty_browser: Chrome/Edge built-in AI for WASM targets All crates compile cleanly against workspace dependencies. https://claude.ai/code/session_01NMtKKc9beRbzKEznEEzQZq --- .gitignore | 7 + Cargo.toml | 85 ++++

The closure now checks whether the local model's CapabilitySet satisfies the request's needs (tool calling, structured output) and falls through to cloud when it doesn't. CacheMiddleware was keying on the prompt alone, so requests with the same prompt but different temperature, tools, output schema, or other generation options incorrectly returned the same cached result. The key now hashes all generation-affecting fields (numeric options via bit patterns, serializable types via JSON, enum variants via Debug). Tests added for both: four router routing scenarios and four cache hit/miss/TTL scenarios using MockLanguageModel.

SSE/NDJSON parse failures now terminate the stream with StreamError instead of logging a warning and continuing as if no data was lost. Affected: Claude (parse_sse_event), Gemini, Ollama (build_ndjson_stream), OpenAI-compatible. 2. Malformed tool-call JSON (accumulated from streaming deltas) now emits a StreamError/Error event rather than silently substituting an empty arguments object {}. Affected: Claude (ContentBlockStop), OpenAI-compatible (flush_pending_tools and inline flush). 3. Transport error source chain was being dropped (source: None) in the Claude and Gemini byte-stream error paths. The original reqwest::Error is now preserved via source: Some(Box::new(e)). 4. The OpenAI-compatible stream parser had an unreachable .unwrap() on a HashMap re-query to extract a call_id that was already bound as `_id` in the pattern match. Fixed to use the bound variable directly, removing the underscore suppressor.

All providers now log a warning and include the read-failure reason in the returned ProviderError message. 2. GeminiProvider::list_remote_models and ChatGptProvider::list_remote_models were discarding the HTTP status code (status: None) after checking it, preventing the retry middleware from distinguishing 429 from 500. Both now capture and forward status: Some(status_code).
