rust-for-tauri

Just enough Rust to write Tauri command handlers — types, ownership, borrowing, error handling with Result/anyhow, async with tokio, and JSON serialization with serde. Use when a Tauri developer needs Rust guidance without learning the full language.

rust-for-tauri

The 80/20 Rust you need to write Tauri backends. Not a full Rust course — just the patterns that appear in every src-tauri/ directory.

Quick Reference

Item	Value
Rust edition	2021 (default in Tauri projects)
Key crates	serde, serde_json, tokio, anyhow, tauri
Entry point	src-tauri/src/main.rs
Command macro	#[tauri::command]
Invoke from JS	import { invoke } from '@tauri-apps/api/tauri'

The Tauri Command Shape

#[tauri::command]
async fn my_command(name: String) -> Result<String, String> {
    Ok(format!("Hello, {}!", name))
}

Every command returns Result<T, String> (or Result<T, E> where E implements Serialize). The Ok value reaches JS as the resolved value; Err rejects the promise.
