open-source JavaScript framework, designed for building apps on multiple platforms. - Code reusability - Hot reload - Javascript ecosystem icon Flutter, is an open source framework by Google for beautiful, natively compiled, multi- platform applications from a single codebase. - Single codebase - Hot reload - Rendering Engine 利用 Rust 重塑移动应用开发 跨平台开发的优势和局限性 Pros: - Fast - Single Codebase - Third-party (Foreign Function Interface) refers to the ability of Rust programming language to interface with code written in other languages, typically C or C++. FFI allows Rust to call functions and use data structures

vector13 constexpr In Everyday Programming • constexpr has steadily increased in power • It's just code that runs on your machine instead of the user's • Example: lookup tables • Everyone uses lookup with T within C structs • Near-identical interface • Encapsulates platform/architecture-specific code • atomic/atomic_ref support wait/notify_one/notify_all20 Highly Artificial Example 🐞 • GH-843 GitHub • Code: linear history, few feature branches • Issues: cxx20, LWG, bug, performance, etc. • Pull Requests: Used for all development • Continuous Integration: Azure Pipelines • Code format validation:

Async code can either… … poll the token periodically to see if stop has been requested, or… … register a callback
