monoio VS config-rs

There is also another thread-per-core implementation by ByteDance (TikTok) for Rust called Monoio with benchmarks[0] comparing it to Tokio and Glommio.

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.

I assume Tokio itself, see e.g monoio or glommio, but also Seastar for C++.

I think monoio is also thread-per-core but also iouring https://github.com/bytedance/monoio. I don't know how you would shard certain keys into different threads, but if you can do that deterministically then there could be a significant speed up.

I believe this is also "thread-per-core".

Bytedance has their in-house monoio <https://github.com/bytedance/monoio> (supports io-uring) but it requires rust nightly.

There's another thread-per-core runtime called https://github.com/bytedance/monoio

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:

https://github.com/bytedance/monoio

https://github.com/DataDog/glommio/issues/554

I see that, I also tried with monoio, but the developer of that runtime mentioned that https://github.com/bytedance/monoio/blob/master/examples/hyper_server.rs might have soundness issues

I like config.rs, but I am struggling to overwrite config profiles with environment variables. The desired config is mixed, like .toml

Consider config crate. It could be like:

I've been using Config most of the time. I also use once_cell to make it a static variable.

I've enjoyed using this one: https://crates.io/crates/config

Anyone know of a library like https://github.com/netflix/go-env but for rust? I found https://github.com/mehcode/config-rs but it's just not as simple...

I was just in that space today. The config crate has an example you might find useful: https://github.com/mehcode/config-rs/tree/master/examples/hierarchical-env

How it differs from config?

Checking an environment variable is very easy with std::env::var or similar. If you have other bits of configuration that also change—which is typical; things like DB connection strings—you may consider a more full-featured solution like https://docs.rs/config/0.10.1/config/ (pay particular attention to this example, which seems to be very close to what you want: https://github.com/mehcode/config-rs/blob/master/examples/hierarchical-env/src/settings.rs ).

It's unfortunate, it looks like there was an attempt to get someone else to maintain it here, but no one ended up really stepping up to the plate.
