Gemini Streaming in Rust + Tauri — Real-Time AI Responses Without the Jank

All tests run on an 8-year-old MacBook Air. All results from shipping 7 Mac apps as a solo developer. No sponsored opinion. Waiting for a full AI response before showing anything feels broken in 2026. Streaming makes the UX feel instant. Here's how I implemented Gemini streaming in Rust with Tauri events. The Approach Gemini supports server-sent events (SSE) for streaming responses. The flow: Rust backend opens an SSE connection to the Gemini API As chunks arrive, emit Tauri ev
