calling-rust-from-tauri-frontend

To call Rust functions from a Tauri frontend, define functions with the #[tauri::command] attribute, register them using tauri::generate_handler!, and invoke them from TypeScript via the invoke API for type-safe IPC.

The best way to pass data between Rust and TypeScript in Tauri is using commands and the invoke API, which provides compile-time type guarantees and supports structured results for reliable data exchange across the boundary.

Tauri supports asynchronous commands for frontend invocation, allowing you to handle async Rust backend logic, return structured results, and propagate errors clearly across the IPC boundary to the TypeScript frontend.

You register multiple Rust commands for a Tauri frontend by passing them to tauri::generate_handler! in your Rust backend setup, making them available for the TypeScript frontend to call using the invoke API.

Tauri commands offer safe, typed communication between Rust and TypeScript with compile-time guarantees, ensuring clean separation of concerns and reliable data exchange compared to direct bindings.

Errors are handled when invoking Rust commands from a Tauri frontend through structured error propagation across the IPC boundary, ensuring clear error reporting back to the TypeScript invoke API caller.
