mini-redis VS case-studies

Hi, I'm trying to implement RESP with Rust (more like a mini-redis clone from tokio tutorial).

One project I found extremely easy to read and understand was mini-redis. Anything similar to that?

For learning async Rust, mini-redis repo is hard to surpass: https://github.com/tokio-rs/mini-redis

The code is simple enough for beginners to follow, but also complex enough to demonstrate Rust async in the wild. And best of all, the code is heavily commented!

You can follow the official Tokio tutorial to implement mini-redis incrementally: https://tokio.rs/tokio/tutorial/setup

for backend async service: https://github.com/tokio-rs/mini-redis

The official Tokio mini-Redis example has a well-documented example of shutting down worker tasks: https://github.com/tokio-rs/mini-redis/blob/master/src/shutdown.rs

Have a look at https://github.com/tokio-rs/mini-redis, written as an example of a modern rust application.

I sure learned a ton from looking at the mini-redis implementation from the tokio team https://github.com/tokio-rs/mini-redis -- especially when you want to work with tokio! I think it's remarkably well structured and documented.

If https://github.com/tokio-rs/mini-redis does not help answer your question, could you elaborate a bit more on your struggle and we can see if we can fit it into our docs.

Tokio async runtime for Rust has a tutorial in its user guide https://tokio.rs/tokio/tutorial on writing a mini-redis (https://github.com/tokio-rs/mini-redis).

You may be able to take inspiration from mini-redis, which is a learning resource created by the Tokio project. Its purpose is to show off many common patterns in async Rust, and a shared hashmap is one of them.

Luckily there is a workaround to emulate such a definition, which dtolnay discovered and explained here: https://github.com/dtolnay/case-studies/tree/b9802f6df8dc8e54970b83fb9af6df923b46abf5/unit-type-parameters.

I think they are talking about this one trick which the devs don't want you to know about. Note that while it looks like specialization, it works only in a few very limited cases and is quite fragile, so it's a hack, not a substitute for the real feature.

Also I suggest his case studies repo since you are looking at what is possible: https://github.com/dtolnay/case-studies

/u/dtolnay has a great case studies repository.

Once you have the basics down, read dtolnay's case studies. They show how to do advanced stuff with easy macros.

If you were writing your own println macro, you might be able to get away with this kind of hack: https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md

You can use "Autoref-based stable specialization" or use/mimic the impls crate.

With a subset of specialization likely riding the trains soon and a workaround available, why would you give up?

this works since values and types are in different namespaces (see: Rusts Universes or dtolnay's Case Study about "Unit struct with type parameters")

To do this with traits you would need specialization but since you are using macros you should be able to use "Autoref-based stable specialization". Here is a playground which uses the latter approach to implement the wanted macro without using any nightly features.
