tauri-ipc

When to use this skill

ALWAYS use this skill when the user mentions:

• Frontend-to-Rust IPC or invoke calls
• Defining Tauri commands
• Type-safe IPC bindings (tauri-specta)

Trigger phrases include:

• "IPC", "invoke", "tauri command", "type-safe", "tauri-specta", "calling rust"

How to use this skill

1. Define a Rust command:
   rustCopy

   #[tauri::command]
   fn greet(name: &str) -> String {
       format!("Hello, {}!", name)
   }
   

2. Register the command in the Tauri builder:
   rustCopy

   tauri::Builder::default()
       .invoke_handler(tauri::generate_handler![greet])
   

3. Call from the frontend:
   typescriptCopy

   import { invoke } from '@tauri-apps/api/core';
   const greeting = await invoke<string>('greet', { name: 'World' });
   

4. For type-safe bindings, use tauri-specta to auto-generate TypeScript types from Rust commands:
   bashCopy

   cargo add tauri-specta specta
   

5. Bidirectional events for Rust-to-frontend communication:
   rustCopy

   app.emit("update", payload)?;  // Rust -> Frontend
   

   typescriptCopy

   import { listen } from '@tauri-apps/api/event';
   await listen('update', (event) => console.log(event.payload));
   

6. Handle errors by returning Result<T, String> from Rust commands

Outputs

• Rust command definition and registration
• Frontend invoke call pattern
• Type-safe IPC with tauri-specta
• Bidirectional event communication
