calling-rust-from-tauri-frontend

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.
