    It's a New Kind of Wrapper for Exposing LLVM (Safely)

    Project mention: Compiler Optimization Learning Suggestions | /r/Compilers | 2023-08-04

    Secondly, I have learned about LLVM, and I have learned about the Inkwell library on Rust (It's a New Kind of Wrapper for Exposing LLVM (Safely)). Has anyone used this library before? Is this a good practice? Is it suitable for my compiler? Can I write some optimization passes of my own using this library?

    Analytical database for data-driven Web applications 🪶

    Project mention: Gcsfuse: A user-space file system for interacting with Google Cloud Storage | | 2023-09-06

    In case you're interested in scale-to-zero database hosting, a few months ago I paired gcsfuse with Seafowl [0][1], an early stage open source database written in Rust. Was a lot of fun balancing tradeoffs that are usually not possible with classical databases e.g. Postgres. Thank you gcsfuse contributors.

    Generate SDKs for your API

    Project mention: Show HN: Hacker News API SDKs → Code Generation in Rust | | 2023-10-17

    Hi Hacker News!

    Patrick and Elias here. We built an SDK / Documentation generator for REST APIs. The link included shows the shiny output of our system: the docs! We generated 5 SDKs and docs from the Hacker News OpenAPI we found on GitHub. If you write code in Python, Typescript, Go, Ruby, or Rust, we’d love for you to try an SDK out!

    If you want to generate SDKs for your own API try our tool here:

    We are both software engineers, and we built this tool because we were spending too much time writing API integrations, supporting integrations, writing documentation, and manually testing APIs at our jobs. We think every engineer can benefit from spending less time on APIs.

    The generator is written in Rust because we need the rich type system, macros, and general correctness emphasis to generate working code. The SDKs are typed, they simplify auth, and they handle files.

    If you want to learn more, check out our complete write up here:

    Thanks everyone,

    PK and EP - [email protected]
