🌘 實作 Bitfields 過程宏 [RUST] - 《LearnixOS 手冊》
➤ 深入淺出：解構 Rust 編譯期的程式碼生成魔法
✤ https://www.learnix-os.com/ch02-03-implementing-the-bitfields-proc-macro.html
本文介紹了 Rust 過程宏（Proc-Macros）的核心概念與運作機制。作者說明瞭宏如何將原始碼作為輸入並輸出新的原始碼，並詳述了 `TokenStream` 如何作為編譯階段處理程式碼的基礎單元。透過與傳統函數的對比，文章解釋了宏如何在編譯期操作原始碼結構，從而實現普通函數無法達成的邏輯注入（如 `break` 控制流），為後續實作 `bitfields` 宏奠定了理論基礎。
+ 這篇文章對宏與函數的本質區別解釋得非常清晰，特別是關於 `TokenStream` 的調試輸出，讓人一眼就能看懂編譯器眼中看到的程式碼結構。
+ 終於理解為什麼 `unwrap_or_break` 這種邏輯不能用函數寫

I made a game prototype with Godot and Rust. Since I got interested in #Rust, I decided to try building a simple game using #Bevy Engine.

If you really like Paperback and Fedra's updater sequence, I made a standalone Rust crate for this functionality. It fetches assets from GitHub, lets you check for development or latest stable releases, shows the markdown release notes in a nice text field, replaces the running binary in both portable and installer modes, etc. Currently Windows only, but that'll change. This is a small part of my broader goal, to make a collection of crates someone can just pick up and start making accessible desktop apps in Rust. https://crates.io/crates/ship-shape #rust #rustlang #wxdragon

crates.io: Rust Package Registry

crates.io serves as a central registry for sharing crates, which are packages or libraries written in Rust that you can use to enhance your projects

🌘 給 Python 開發者的 Rust 入門指南
➤ 從 Python 優雅轉身：打造高效能的 Rust 系統開發思維
✤ https://microsoft.github.io/RustTraining/python-book/
本書專為擁有 Python 經驗的開發者量身打造，旨在引導讀者平滑過渡至 Rust。全書將 Rust 的學習過程拆解為三個階段，由淺入深地探討從動態型別、垃圾回收機制轉換至靜態型別與記憶體安全系統語言的核心差異。透過清晰的學習路徑、循序漸進的練習以及實作專案，幫助開發者掌握 Rust 的記憶體管理、所有權機制（Ownership）及併發處理等核心概念，並提供 Python 與 Rust 的語法對照，縮短學習曲線，提升系統級程式開發能力。
+ 這份學習地圖非常實用！對於習慣了 Python 這種動態語言的人來說，Rust 的所有權（Ownership）確實是最大的門檻，將章節區分為難易度並附上實作目標，讓人更有方向感。
+ 終於有針對 Python 背景設計的教材了。特別喜歡關於 PyO3 的章節，
