SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Frontend apps built with Tauri often need to call into Rust backends to perform privileged or performance-critical tasks. This skill provides a structured approach to expose Rust functions to the frontend using the #[tauri::command] attribute and the invoke system, including argument serialization, error handling, and async support.

Core Features & Use Cases

Define a Rust command with #[tauri::command] and expose it to the frontend
Register commands in a single invoke_handler! call for predictable routing
Invoke commands from TypeScript/JavaScript using the invoke API and receive typed results
Support async commands and proper error handling with Result<T, E> and serialization

Quick Start

Define a tauri command in Rust, register it with generate_handler!, and call it from TypeScript using invoke.

FAQPage Schema

How do I call Rust functions from a Tauri frontend?▼

You call Rust functions by defining them with the #[tauri::command] attribute, registering them in a single generate_handler! call, and invoking them from the frontend using the Tauri invoke API to execute backend logic.

How does Tauri IPC invoke handle argument serialization?▼

Tauri IPC invoke handles argument serialization by requiring command inputs to implement the Deserialize trait and outputs to implement the Serialize trait, ensuring typed data is correctly passed between the frontend and Rust backend.

Can I run async Rust commands from a Tauri frontend?▼

Yes, you can run async Rust commands from a Tauri frontend. The Tauri invoke system fully supports async commands, allowing the frontend to call into Rust for non-blocking data processing, IO operations, or system interactions.

How do I register multiple Rust commands in a Tauri app?▼

You register multiple Rust commands in a Tauri app by listing them all together in a single generate_handler! invoke_handler call. This ensures predictable routing when the frontend invokes specific backend functions.

What is the best way to handle errors when invoking Rust from Tauri?▼

The best way to handle errors when invoking Rust from Tauri is returning a Result<T, E> type from your command. Both the Ok and Err variants must implement Serialize to correctly propagate typed errors to the frontend.
