    Project mention: Recommendations on file/dir/module structure, common dependencies, and/or anti-patterns for writing CLI tool in Rust | | 2023-03-18

    The main focus of the CLI tool would be around working on filesystem, and also making several network requests simultaneously. Although some may argue it would be easier/faster writing in other languages, this is more for my own learning to write in Rust. It will be a simple toy project at first, but I'd like to prepare for more complex Rust programming in the future with it. For instance, I see different directory / file / module structures used, Rust version / edition differences here and there, some common dependencies such as Tokio, etc.

Except for wireguard, these are commercial platforms, the open source alternatives I know of, are (respectively):

    Project mention: Tokio for FFI app? | | 2022-12-13

    Project mention: tcpdump is amazing (2016) | | 2023-02-02

    > I mentioned really briefly that tcpdump lets you save pcap files. This is awesome because literally every network analysis tool in the universe understands pcap files. pcap files are like freshly baked chocolate chip cookies. Everybody loves them.

    OMG, yes, very well put. When I get a bug report with a pcap file I know I'll be able to know exactly what happened.

    Speaking of which: for one of my libraries, I want to make a diagnostic tool that replays an interaction. My library mostly operates at the TCP level (also some UDP), so I need to reconstruct the TCP flows in my tool to feed to my library. Either I need an easy-to-use Rust library to do that directly from pcap files [1] or some format that represents bytes moving over the flow (like sets of lines with a timestamp, flow id, and pretty hexdump of the bytes) with a tool that produces it from pcap. This seems like something that should exist? Wireshark's “Analyze > Follow > TCP Stream”’s “Save As…” with "hex dump" is kind of what I want, but it doesn't have timestamps, and it doesn't have a way to put everything (multiple flows, UDP packets also) in one file.

    [1] looks promising but it wasn't as obvious as I hoped how to plug it in for what I want.

  • shadow

    Shadow is a discrete-event network simulator that directly executes real application code, enabling you to simulate distributed systems with thousands of network-connected processes in realistic and scalable private network experiments using your laptop, desktop, or server running Linux. (by shadow)

    It is no longer active. If you are asking about Shadow, check out

  • ntex

    framework for composable networking services

    Project mention: Benchmark of most widely used rust web frameworks | | 2022-07-16


  • zenoh

    zenoh unifies data in motion, data in-use, data at rest and computations. It carefully blends traditional pub/sub with geo-distributed storages, queries and computations, while retaining a level of time and space efficiency that is well beyond any of the mainstream stacks.

    Project mention: Zenoh Performances | | 2023-03-27

    As some of you may already know, Zenoh is a pure rust pub/sub/query protocol that runs on pretty much anything (including microcontrollers) and abstracts, with a few simple primitives, pub/sub, distributed queries and distributed computations.

  • laminar

    A simple semi-reliable UDP protocol for multiplayer games

    Project mention: Choosing a networking library for my game | | 2022-05-06

    enet - Golden standard, tested and reliable - Not native rust - Does not seem to be popular in rust turbulence - Readme says it is not stable, but last meaningful commit was 1 year ago - Lacking documentation and examples - Not very popular laminar - Last meaningful release was 3 years ago (ignoring changes that fix typos etc.) - Despite this, everywhere (book, readme) there are mentions that it is under "active development" - Created for Amethyst, which is dead. I am kinda fearful that the same thing will happen to this lib. Tachyon - New and not tested in the battle - Many features that other libraries have planned, Tachyon actually has implemented - Lacking documentation (except for one big readme file), tests, examples Quinn - Big, under active development (daily commits), very popular because web development. - Modular, ability to just use core implemetation: quinn-proto - Do i really need TLS certificates and cryptography for my playing with friends game server? - Stream based, I would need to implement recv/send messages on top of it (not that hard tbh) - Only reliable stream and "unreliable" messages.

    Project mention: What's everyone working on this week (12/2023)? | | 2023-03-20

    I've been working on a rust-native implementation of our agent protocol here at ngrok. It's something I've been wanting to do for a long time (since I started working here really), and I'm excited for it to be nearly "launch-ready"! It's already public on GitHub or, but we should be making some sort of "real" announcement Soontm. Feedback is welcome and appreciated!
