coming soon. 2.3 Unified runtime for eBPF and Wasm Summary II. Practicing Sparrow  Our previous talks "GraalVM-based unified runtime for eBPF & Wasm" at GOTC 2021 (Shenzhen) & "Revisiting "Revisiting GraalVM-based unified runtime for eBPF & Wasm" at OpenInfra Days China 2021(Beijing), and the third-round discussion of this topic will come in this year, which includes Development build the Renode Rust UART peripheral example: cargo build --target wasm32-unknown-unknown --release --lib III. Sparrow Development on branch "26999-rust_uart":

2014 ~ 2018 Some small projects • 2020 ~ 2021 More open-source projects, gomoku, youki, dapr-wasm • 2022 ~ Regular contributions to Rust My Rust experience • A real case Remove duplicated diagnostics

架，让开发者能够使用简单的 Rust 写 应用 如何用 Rust 实现的 构建和部署 AI 相关工作流的 serverless 平台 • 上传 Rust function ，平台负责将 Rust 编译成 Wasm ，并运行在 WasmEdge 安全容 器中 • 平台封装了一些常用 LLM 和 SaaS 的 API ，并发布成了 crate ，比如 ChatGPT 、 telegram 、 GitHub
