  • What's the canonical way of doing it in rust?
    1 project | /r/rust | 16 Oct 2023
    Was playing around with mio (https://github.com/tokio-rs/mio) (not that mio itself is very important here!) and was trying to implement a simple something that I've done in java before: a Reactor that you can register ReactorClients with that will get callback whenever there are events on the corresponding socket etc.

    How does it compare to mio?
  • How does the Rust mio crate implement deregistering connections?
    1 project | /r/rust | 22 Oct 2022
    TcpStream gets its wake behavior by delegating to the fd wakers. The Unix wakers have a few implementations, for different platforms. On Linux and Android, epoll is used.
  • Looking for Tokio's event loop source code
    4 projects | /r/rust | 11 Oct 2022
    The real implementation details of the I/O event queue is done in mio as u/hniksic pointed out, but that's more comparable with libuv which is certainly a huge part of the Node runtime. mio and libuv have a lot of similarities (at least they used to).
  • Python multi-level break and continue
    6 projects | news.ycombinator.com | 3 Sep 2022
    My example was "twice by one developer", not "twice across all indexed repos."

    A spot check shows that quite a few in your link are used specifically to ensure correct handling of Rust multi-level breaks work syntax, like https://github.com/rust-lang/rust-analyzer/blob/master/crate... , https://github.com/rust-lang/rustfmt/blob/master/tests/sourc... , https://github.com/rust-lang/rust/blob/master/src/tools/rust... , https://github.com/rust-lang/rust/blob/master/src/tools/rust... and likely more.

    Another is a translation of BASIC code to Rust, using break as a form of goto. https://github.com/coding-horror/basic-computer-games/blob/e...

    The example at https://github.com/tokio-rs/mio/blob/master/tests/tcp.rs is a nice one

  • Crates to help with event-loop type pattern?
    1 project | /r/rust | 17 Aug 2022
    In my program, I have about 6 different components that follow the pattern below. Basically, the components run a thread while polling on crossbeam channels, file descriptors or sockets. For polling, I am using Mio (https://github.com/tokio-rs/mio).
  • Ask HN: Has any Rust developer moved to embedded device programming?
    9 projects | news.ycombinator.com | 17 Aug 2022
    On the code side it's pretty much the same as C++. You have a module that defines an interface and per-platform implementations that are included depending on a "configuration conditional checks" #[cfg(target_os = "linux")] macro.

  • What is the point of async and await?
    1 project | /r/rust | 15 Apr 2022
    Indeed! In practice it's done through the polling operation: instead of a separate poll for op1 and op2, the program essentially tells the OS "wake me when either op1 or op2 is ready" (through the epoll syscall on Linux). The mio crate implements this, and the example on the readme is basically the same loop, but written with this polling strategy in mind.

  • Gazette: Cloud-native millisecond-latency streaming
    6 projects | news.ycombinator.com | 7 Aug 2024
    I feel a bit paralyzed by Fear Of Missing Io_Uring. There's so much awesome streaming stuff about (RisingWave, Materialize, NATS, DataFusion, Velox, many more), but it all feels built on slower legacy system libraries.

    It's not heavily used yet, but Rust has a bunch of fairly high visibility efforts. Situation sort of feels similar with http3, where the problem is figuring out what to pick. https://github.com/tokio-rs/tokio-uring https://github.com/bytedance/monoio https://github.com/DataDog/glommio

  • I want to share my latest hobby project, dbeel: A distributed thread-per-core nosql db written in rust
    3 projects | /r/rust | 13 Nov 2023
    I used glommio as the async executor (instead of something like tokio), and it is wonderful. For people wondering whether it's "good enough" or to use C++ and seastar (as I have thought about a lot before starting this project), take the leap of faith, it's fast - both in terms of run time and to code.
  • The State of Async Rust
    9 projects | news.ycombinator.com | 25 Sep 2023
    My understanding is you always need a runtime, somethings needs to drive the async flow. But there are others on the market, just not without the.. market domination... of tokio.

    https://github.com/smol-rs/smol looks promising simply for being minimal

    https://github.com/bytedance/monoio looks potentially easier to work with than tokio

    https://github.com/DataDog/glommio is built around linux io_uring and seems somewhat promising for performance reasons.

    I haven't played with any of these yet, because Tokio is unfortunately the path of least resistance. And a bit viral in how it's infected tings.

  • Learning Async Rust with Too Many Web Servers
    4 projects | news.ycombinator.com | 18 Aug 2023
    I think you missed one which is based on io_uring [1].

    In my benchmarks with a slightly tweaked version it was 2x faster than Nginx and and 30x faster than Python's SimpleHttpServer.

  • How much reason is there to be multi-threaded in the k8s environment
    2 projects | /r/scala | 4 Jul 2023
    b) It's proven now e.g Seastar, Glommio that the fastest way to run a multi-threaded application is to have one instance with one thread pinned per CPU core. Then to have fibers/lightweight threads on top handling all of the asynchronous code. Your approach of lots of instances is the slowest so there will be a ton of unnecessary thread context-switching.
  • Why does Actix-web's handler not require Send?
    3 projects | /r/rust | 18 Jun 2023
    I assume Tokio itself, see e.g monoio or glommio, but also Seastar for C++.

  • Use io_uring for network I/O

    > Few of us have really figured out io_uring. But that doesn't mean it is slower.

    seastar.io is a high level framework that I believe has "figured out" io_uring, with additional caveats the framework imposes (which is honestly freeing).

    It's worth mentioning: Under "Async Executors", for "io_uring" there is only "Glommio"

    I recently found out that ByteDance has a competitor library which supposedly has better performance:
