I want to study Rust's async/await concept more deeply. I've seen some synthetic examples already and now I'm looking for a nice open-source project that could help me see how this approach is used to solve real-world problems.
The mini-redis project was written to help teach use of tokio, which is the most widely used async runtime, so I imagine it would work well for learning practical async in general as well. Strictly speaking it's not solving a real-world problem since it's incomplete and written purely for teaching purposes, but you may find it useful regardless.
